India's new bullet trains will be customised to suit the subcontinent's climate conditions

"bullet trains even at 320 kmph. The E 5 Series Shinkansen will “compensate” for any roll and will also be modified to meet harsh Indian hot weather conditions and omnipresent dust."

“The environmental conditions in Japan are different. Initially, we thought we will bring the trains lock, stock and barrel since it’s time tested. But when we went into detail, we discovered that the temperature and dust conditions are creating a big difference. In our ambient temperature, we are asking for 55 degree centigrade; they design for 40 degree...15 degrees in air conditioning will make a big difference. The air conditioning equipment will be very heavy and they have very compact design. So, accommodating that increased equipment will be a challenge.”

SWR on a roll.

1. Central air conditioning started and set at 23.5 C in the new terminal building Sir M. Visveswaraya terminal Bypannahalli.

https://twitter.com/Lolita_TNIE/status/ ... 9392897024

2. Doubled and Electrified line commissioned between Yelahanka and Makalidurga,(36 km) speeds are a bit slow, only 75 kmph in the ghat section Oddarahalli to Makalidurga(one block section) and 90 kmph Yelahanka to Oddarahalli.

https://twitter.com/drmsbc/status/13645 ... gr%5Etweet

Coimbatore--Kurla exp. was the first train on new tracks. These tracks will alleviate system overloading between Bangalore to Mumbai and Bangalore to Delhi. Makalidurga to Devarapalli(next to Hindupur) (36 km) doubling and electrification was commissioned in April 2019.


Now left is Devarapalli to Penukonda(48 km) that SWR claims will be doubled and off course electrified by June this year. Video shows works between Devarapalli and Penukonda, track linking in many block sections. Penukonda---Anantapur---Dharmavaram----Gooty/Guntakal in SCR territory many sections are doubled already and doubling is going on well.

3. Hubbali yard now SSS Hubbali Jn. had a 2 month long yard re-modeling prior to doubling works that are finished between Guntakal ---Ballari---Hospet---Gadag----Hubli----Londa---Tinaighat. Electrification on this route will soon be over, RE is only left around Hubli for about 50km. South Bangalore to Hubli doubling is getting finished in a year and a half 100 km left and electrification here has reached Tumkur. So major changes had to made. The massive yard is now 6 times its original size. Due to space constraints they are building the longest platform in the world. Yard was commissioned yesterday.

Press Release of SWR listing salient points accomplished by Hubbali yard re-modelling commissioning on Feb 24, allowing simultaneous reception
and dispatch towards Gadag, Londa on double line and towards Bangalore when doubling is complete between
Hubli and Davangere.

88 new Railway projects were dedicated to the nation few days ago by PM Modi. Numerous things like FOBs in Kerala and RUBS in Goa etc.

1. Important take aways Jhargram to Kalaikunda third line which was commissioned a few days ago, on the Kharagpur-Tatanagar east-west route will help in decongestion.

2. Long pending project on CR, 17 km third line between Itarsi and Nagpur in the ghats/Satpuras. Ruling gradient here between Chichonda and Teegaon is 1:65 which is quite steep and there are also catch sidings for run away trains. This is part of the Delhi to Chennai/Hyderabad third line project. Commissioned Dec 2020 also dedicated to the nation among the 88 projects.

3. RVNL has announced that Tunnel-5 in the Barkheda to Budni 23 km ghat section between Itarsi and Bhopal is through in the Ratapani tiger reserve. This will also carry the third line between Chennai and Delhi. Once this 23 km is finished(Tunnel 1 at 1085 m the longest is also done, 5 tunnels in all)
Bina to Itarsi is tripled a very big section of 240 km will be tripled, almost the entire section in WCR between Delhi and Chennai is tripled.

https://twitter.com/RailVikas/status/13 ... 3831402496

Tunnel-5 can carry two lines, possibly they might eliminate the famous Bulb ghat double line currently using a straighter alignment for lines 2 &3. Tripling is going on between Chennai and Delhi on its entire length and also in the dedication to the nation, PM Modi dedicated the 4th line Chennai Beach to Attipatu on the Chennai to Gudur section towards Delhi, Howrah and Hyderabad from Chennai which is very congested.

Suraji... This is nothing new. Search for Navi Mumbai railway stations and you will find them on a similar layout. Made of course nearly 2 decades ago by CIDCO.

Yes I know - I have family nearby in Vashi, Kopar Khairane, Nerul and elsewhere, and saw it when it was first built :) However CIDCO built showpieces of the suburban rail of a planned city is different from a standard IR station in a tier 3 city, even a state capital. It’s good that IR is letting private companies do this - they don’t need to be in the business of building stations,

Really slick video from Alstom India about their contribution to the DFC work:

Lots of interesting drone visuals, and an inside view of the massive OCC in Prayagraj (nice of them to use that name correctly).

At least in DFC they have started off with the centralised signalling concepts. I wish the same would also be soon introduced in other sections as well. Even today IR uses a very old concept of sections & section controllers to monitor the movement of trains. For each and every train movement a station master generally calls up the section controller to confirm what has to be done with the train (run through?, detain? etc.). This is now becoming a bottle neck in routes which there is a train pretty much every 7-15 mins. This along with the need to close level crossings etc adds to the overall delay in running the train.

Track linking and laying has started using NTC machines on the 127 km line that encircles NCR region around Delhi and links the end of the EDFC at Dadri to the start of the WDFC at Rewari. 10km is already laid. Machines lay 1.5 km of track a day with great precision. L&T is the prime contractor. This line passes through the recently excavated Sohna tunnel and the very long Sohna viaduct as well as the already prepared bridges over Rivers Yamuna and Hindon and over the Delhi to Chennai/Mumbai main line using a already ready rail over rail viaduct.

An animated view of what this 127 km section entails(so you can see what I am talking about, Sohna tunnel and viaduct and the various bridges and rail over rail flyover at Asaoti station on the Delhi to Mathura section)

https://www.youtube.com/watch?v=ld5yNKZJ62Y

First rail over flyover seen is Delhi-Jaipur double line at Karnawas. Then the rail flyover seen after DFC station New Pirthala is the Delhi-Mathura four lined track. This rail over rail flyover bridge was done by a mega block on Jan 26, 2019.



Late March the Madar(Ajmer) to Palanpur in Gujarat section of the WDFC is due for commissioning. Here is how axle counters work on the WDFC:

No week goes by nowadays with a spate of CRS inspections taking place. The CRS inspectors who are under the Ministry of Civil Aviation with their HQ at Lucknow(where RDSO is also located) are scurrying around India frantically to keep up with doubling commissioning, railway electrification, new lines etc. This formerly moribund office with its commissioners for various zones are all over and being given lots of work.

1. A few days ago Abdul Latif Khan CRS NER region was in Pilibhit to inspect Pilibhit to Bareilly RE under Izzatnagar division of NER. Yesterday he again returned as he had to inspect Tanakpur to Pilibhit RE. Now he will come back again for Shahajanpur to Pilibhit RE etc etc. Soon Izzatnagar division will see everything under wires anyhow 160 km is all that is left there for all wires. And if you think that is not enough he was doing RE and doubling inspection last week between Sitapur and Roza Jn(Shahjanpur) between Jung Bahadur Nagar and Bartara.

2. Southern zone CRS is running around too. 15th he is doing doubling inspection on SWR new track on Londa to Miraj section between Raybag and Kudachi. 16th Davangere to Tolahunse. That will essentially now leave 123 km for doubling Bangalore to Hubli and by June 100 km left.
This man will again be called soon for RE Tumkur to Bangalore soon. As if that is not enough, SWR had him checking 65 route km from Hubli to Alnawar RE (now FEDL) on the Hubli to Goa route and the poor chap had to in the same week check RE between Hospet and Harihar and a day apart RE from Palakoddu and Peringunthanai on the Bangalore --Hosur---Salem route.
These chaps probably have had their family lives destroyed by this very evil Mudi, he must shurly rejine.

3. And if the South zone Commissioner did not have his plate full, he was before all that happened in part 2^^^ checking the new double line deep in South Tamil Nadu(whatever happened to this colorful phrase on BRF) between Gangaikondan and Tirunelveli on the Madurai---Nagercoil---Kaniyakumari doubling project that SR is completing quite fast by doubling sections that are really clogged first This guy is soon going to go back as Milavattan to Thataparai (Tuticorin to Vanchi Maniyachi section) doubling is also finished or nearly so thus establishing doubling between Thootukodi port and the spine of India and also doubling between Tulukapatti and Kovilpatti on the same Madurai to Kanniyakumari route.

https://www.thehindu.com/news/cities/Ma ... 926102.ece

I do not even want to write the hell that has now begun to visit Eastern zone Commissioner , RE Coochbehar to the gates of Guwahati(Rangiya), West zone guy is going crazy also, Udaipur to Ahmedabad re-gauging. Hell on wheels happening.

And now for the first time I see earthworks on Google Earth near Surat for the Mumbai to Ahmedabad high speed rail project. This is the first time anyone has said anything about it here. L&T seems to be moving quickly. It runs close to WDFC but crosses Tapi river closer to Surat city. Not as developed as WDFC but for sure you can see it and faint traces of piers also. Here it is:

Indian Railways increases line capacity on Mumbai-Delhi route; operation time to reduce.

Indian Railways in an effort to reduce the travel time on the busy Mumbai-Delhi route has recently undertaken the remodelling work of Vadodara Yard.

The Western Zone of Indian Railways has also commissioned Centralised Electronic Interlocking which will help in reducing the detention time of trains on the busy Mumbai-Delhi route.

The project was termed as one of the “super critical projects" of the Indian Railways since the yard lies just on the north of Vadodara on the extremely busy Delhi-Mumbai route.

According to a senior railway official, "The remodelled Vadodara Yard will help in segregating rail traffic of Ahmedabad and Ratlam sides. On 13 March, the non-interlocking work was successfully completed and Vadodara Yard electronic interlocking was commissioned."

"During the remodelling work, 3 signalled loop lines in UP direction were provided, which will help in train regulation and preference. Along with this, goods bypass lines 1 & 2 were made for passenger trains, which will be utilised to run passenger trains if required," the official said.

The line capacity in the earlier super congested Vadodara area has now been increased, with this 8 permanent speed restrictions were also removed.

The merger of C and D cabins into centralised Electronic Interlocking will reduce the operation time and will save manpower.

Besides this, 66 old points were removed and 32 new points were inserted. This will reduce frequent maintenance & renewal costs, along with reduction in failures. Two diamond points were also eliminated which will help in reducing maintenance and improve speed & security.

The railway official stated that during the remodelling work, 325 km of new cables have been laid, 235 routes Electronic Interlocking commissioned, 35 mains signals and 35 shunt signals have been commissioned, 67 new point machines installed and 115 track circuits have been laid.

Due to the remodelling, Accident Relief Train (ART) can now be directly dispatched from Vadodara Yard to Ratlam side. This was not possible earlier. The nomenclature of lines in the yard are now simplified, which makes coordination easier. A Centralised Operations Centre has also been commissioned which is constructed by NHSRCL on the pattern on Air Traffic Control and offers a 180 degree view of the yard.

Any idea on what Centralised Electronic Interlocking means? Is it about having a central control from where tracks for a very large distance can be monitored and trains controlled? Some thing like what happens at Chennai Suburban network? AFAIK the entire suburban train movements are controlled from a central location at Arakkonam (AJJ).

IR was any was upgrading the signalling systems at big railway junctions and yards to be of RRI (Route Relay Interlocking) types. But here again, once the train leaves these places individual SMs on small stations still had to take instructions from the Section Controllers and then set the routes & change signals (which all introduced delays in train running).

PS: UK seems to have moved to the centralised command & control for trains very early. Remember reading that entire route after London X Cross yard was controlled from Peterborough nearly 100 miles away.

^^^ I believe several smaller cabins in Vadodara yard like Cabins C, D got consolidated as one central place from which movement through Vadodara yard can get directed. Mumbai suburban has a centralized control room and Chennai suburban, but beyond that there is no centralization yet other than DFC. Apparently one can get a 360 degree view like an ATC of the entire yard at Vadodara from the new layout. They had done some earlier work at the start of Covid-19 by breaking up washable aprons etc which had become a hindrance to elevated speeds through the yard. Now they have removed 8 permanent cautions through the yard. Maybe the speed on the run through line is 110 kmph at the least.

The CRS on 20 km doubling Kudachi to Raybag on SWR Londa--Miraj--Pune section was done at 130 kmph with no peaks observed. Davangere to Tolahunse doubling was done next day 9km at 110 kmph. Essentially now Bangalore to Hubli is doubled to beyond Amravathi colony leaving about 100km of doubling. RE is almost done Bangalore to Tumkur with poles to be erected just at Tumkur. Most likely they will start MEMU services to the city once completed. A little bit of RE work has started towards Hubli beyond Tumkur at Bannasandra.

IR is focusing also on feeder lines into the DFCs. In the last three days they finished CRS for RE and signals and points upgradation on a sleepy branch line with semaphore signals unbelievable, from Unnao to Sitapur in Terai region. Unnao is 20 km from Kanpur. Also the branch line that splits off from the Kanpur Kasganj line at Mandhana/IIT Kanpur gate, RE is commissioned after CRS so MEMU services from Bithoor can start. Bithoor is a pilgrim spot and has the ruined palace of Nana Rao of 1857 fame and a biking spot for old timers IIT students. There is a plan mooted to continue this dead end line across Ganga by a new bridge to join the Kanpur to Lucknow line near Lucknow at Sonik. Kanpur to Lucknow 85 km is being upgraded to semi-HSR status at 160 kmph as the two cities have become one long connected sprawl nowadays, far cry from 65 years ago.

If this new line Brahmavart/Bithoor to Sonik is built, DFC traffic from Bhaupur can completely bypass Kanpur Central and cross the Ganga on the outskirts to Lucknow, Gorakhpur etc. Right now any and all trains to Lucknow from Delhi via Kanpur have to go through Kanpur station. There is no room in Kanpur Cantt for third lining Kanpur to Lucknow and the old railway bridge on Ganga has all sorts of cautions on it and needs replacement. Beyond Magarwara and Unnao too the population density is crushing and there is no room for third line. The Bithoor to Sonik line will go through boonies and so LA will be difficult but easier.

Speed trial at 100 kmph + on WDFC between Madar(Ajmer) and Marwar today 20th March

https://www.youtube.com/watch?v=fkK4m0dUQzs

Section is to be opened by end of this month along with Marwar to Palanpur(Gujarat) with connectivity to Gujarat ports, Kandla, Pipavav and Adani ports.

ROB launching yesterday on WDFC at Vedchha between Billimora(Gujarat) and Surat.

https://www.youtube.com/watch?v=zs8jrYmILko

Notice the already constructed WDFC tracks (extreme left, crane is over the tracks, you can see the dust from fresh ballast, right most 4 tracks are Delhi -Mumbai with two through and two loop lines through Vedchha station which can also be seen) and the four other( 2 loop lines and 2 through lines ) Delhi--Mumbai main line WR tracks. Notice OHE masts are different heights on IR and DFC.

The JNPT spur section is worrying with the instability in MH. You cannot have double stack container traffic from JNPT as IR masts are 5.6m high. So cannot say container trafffic will move on IR and then get onto DFC at say Vasai. No can do unless single stack. Amazing how many people cannot apply basic logic on Internet. Connection with high mast OHE is a must to JNPT or one loses functionality and purpose of WDFC.

I hope they dredge out the pond below the "Towards ICD" array at 1:04 in this video and build the track on pylons, and not fill up the pond. We can use all the waterbodies possible.

Indian Railways to increase the number of trains operating with 'HOG' technology.
Indian Railways' South Eastern Railway(SER) zone has decided that it will remove one of the power coaches(generator cars) which is used to provide electricity in the passenger coach and will replace it with a general coach.

The addition of the general coach will help more people travelling in these passenger trains of the Indian Railways.

The SER zone said that "Six trains and will run with only one power car instead of two cars and will operate with 'Head-On-Generation(HOG) technology.

With the introduction of 'HOG' technology, Indian Railways will be able to save on the consumption of diesel which is used to power the generators. The train will now draw power from the Over Head Equipment(OHE) to carry on the electrical requirements in the train.The HOG technology is used to draw power directly from the electric traction to meet the requirements for devices running on electricity like air conditioners, electric bulbs, and fans.

The HOG system does not require any diesel oil consumption and as such will reduce air pollution and also noise pollution. In addition, it also provides uninterrupted illumination in the coaches.

Construction of the last of the bridges over Yamuna of the DFC. DFC has three bridges over Yamuna. This single track bridge lies between Saharanpur and Ambala between Sarsawa and Jagadhri. The one near Dadri on the Dadri to Rewari 127 km section double lined, already complete by L&T. Another at Prayagraj on EDFC double lined that is being built using a launcher and is slow. Piers are ready at Prayagraj. 7 spans were left to launch.

^^^ Coffer dam is being constructed to lay the foundation of piers. Spans launched by either pushing or lifting into place. Fastest method to build the bridge. There will be two DFC stations here, New Jagadhri and New Kalanour, both as soon as the train crosses the bridge in the direction of movement in the video. Train is going towards Ambala from Saharanpur. One coffer dam seems to be incomplete and being built to build a last remaining pier. Two gen sets can also be seen.

In February one of the tunnels on the Bhanupali to Leh line achieved breakthrough. In the first phase Bhanupali---> Bilaspur(Himachal Pradesh)---> Beri 65 km is being constructed with 7 tunnels and 9 bridges. Most of the tunneling uses NATM method. This is a strategic line and there is no word on whether this line will be built all the way to Leh which is total length 458km. At least 65 km is being built in Phase 1. The entire project if implemented has 9 phases. Total cost was projected at 84,000 crores upto Leh which is possibly going to be exceeded if built. The highest station in the world will be on this line at Tanglang La at 17, 582 ft if built to Leh. Due to oxygen depletion, e-locos will be doing the hauling as diesels will encounter a penalty.

Even completion of this segment to Beri village was scheduled for completion March 2025 in a presser by last CRB V. K. Yadav.

Bridge 40 and tunnel on the Jiribam--Imphal line scheduled for completion Dec 2022. 47 tunnels on the line with 46 complete.

Loco trials using GE diesels WDG-4G locos are taking place between Madar(Ajmer) and Palanpur preparatory to commissioning this section of the WDFC, Rewari to Palanpur 650 km. Once commissioned, Gujarat ports will be connected through Samkhiyali---Palanpur and onto the WDFC. Pipavav, Mundhra and Kandla ports. The line from these ports to Palanpur is being doubled and electrified by high mast OHE to facilitate double stacked container traffic to flow to the WDFC. Several sections on this feeder route are already doubled and you can see these videos I have posted earlier. By next year June the project will be finished and this important feeder route will be doubled and have high rise RE for double stacked container traffic.

Cut and connecting interlocking work connecting WDFC to IR is also going to be done on this section on April 6th New Bangurgram and April 10th at Marwar. This is preparatory to making Madar to Palanpur WDFC operational. Uske baad, Thakre apna JNPT ko saath lekar baith jao. By June for sure a fast way for container traffic to reach Kanpur, UP and Delhi and Punjab area. Once Madar to Palanpur is commissioned in a few weeks, 1000+ route kms of DFC is done and operational.


Loco trial on Third line between Kavali and Ullavapadu 29km at 120 kmph the first section to undergo third line trials on the congested Gudur--Vijayawada section that carries both Howrah--Chennai and Chennai -Delhi traffic and Chennai--Hyderabad traffic. Third line work is also reaching final stages here near Nellore with bridge across Penna river ready. Kavali---Bitragunta ---Nellore should be commissioned soon in a year. Line tripling is going on all the way to Delhi from Chennai. Today was CRS third line Jhansi to Babina. Bina to Bhopal 123 km is tripled and Bhopal to Itarsi tripled except for 23 km ghat section with 5 tunnels, completion next year. Balharshah to Kazipet 55 km tripled. Itarsi to Nagpur 17 km in the Satpura ghats tripled. Now this happening in the tail Gudur to Vijayawada.

WCR installs cameras and voice recorders on 10 locos so that in case of an accident one can use the cameras to identify the cause and provide evidence. 6 cameras in each loco, two in the cab and some mounted outside to view the track including OHE equipment.

The cameras can be monitored real time by a control room.

First freight ran today on WDFC between Palanpur(Gujarat) to Rewari(Haryana) 643 km to Bawal in Haryana. 50 tankers hauled by twin chugging ALCO diesels(Jhansi diesel shed). They will test OHE in next phase by running elocos. OHE is installed and charged and trials have taken place using elocos.

Thakre is not the only useless CM. That Jagan of AP is also a moron. Here is how he obstructs infra.

https://bangaloremirror.indiatimes.com/ ... &prtpage=1

AP reneged on paying for part of the cost for Bengalaluru---Hindupur---Penukonda doubling and RE project after agreeing to it. This is the key line North out of Bangalore towards Mumbai and Delhi. Railways is doing it on its own now. AP is another gone case state or slowly becoming one.

The new wagons being tested by RDSO(oscillation trials) that will have the capacity to run at 100 kmph and with 25 ton axle loads on the DFC. DFC is designed and constructed for 32 ton axle loads for the future.

https://www.youtube.com/watch?v=_izGkSDzihU

IR train on the right towards Delhi on the Ahmedabad to Delhi line and the inaugural freight from Palanpur on WDFC ^^^ at Sendra in Rajasthan. Sendra is a ghat section. Notice how high the DFC tracks are compared to IR. IR recently doubled this section too.

https://www.youtube.com/watch?v=jhIsDlWmE0Y

The high embankments are to maintain a 1:200 grade a design requirement of both DFCs.

Update on the Dhansiri(Assam)---Zubza(Kohima)/Nagaland new rail line 82 km.
20 Tunnels in all, 19 major bridges. To be built in 3 phases but is now way, way behind schedule due to incompetent state government and lack of cooperation in land acquisition. An interview with Pritam Baidya, project engineer on Tunnels 1, 1A, 2,3 is linked below. The last three are done but lining work is going on. Tunnel 1 900m done out of 3.2 km but they have hit poor strata and water seepage and so Tunnel 1 progress is delayed. They would want to start another portal at the other end but LA issues have intervened(not said in the interview). Recently there is word that the LA issues at the opposite portal has been resolved and so possibly tunneling can go on at both ends. Tunnels 1-3 are near Chumoukedima village.

Meanwhile engine rolling took place for 8 km from Dhansiri(Assam) into Nagaland(upto Dhansiripar, Dimapur distt.) and the locals climbed onto the engine.

https://morungexpress.com/dmr-zubza-rai ... ortie-only
Dhansiri to Shouxuvi(30km) was to have been done in first phase and this is roughly flat ground. The next 50km is hills and mountains. Engine rolling took place in the first phase part for 8km.

Another 100 km of track opens up on EDFC with an Alstom loco pulling freight between Ganj Khwaja and Chiraila Pathu. Ganj Khwaja is the first station after DDU Deen Dayal Upadhyay (formerly Mughalsarai) on the Grand Chord.

https://www.youtube.com/watch?v=3JkxXCDoUng
Chirail Paithu is beyond Dehri on Sone, so that means other than the loop around DDU, EDFC is complete between Dehri on Sone to Mughalsarai. So EDFC is complete on all sections in Bihar except the PPP sections between Dehri and Dankuni in WB. Hopefully this will now move faster after Mamta demits office. So EDFC left now between Kanpur and DDU/Mughalsarai(inc). DFC will not enter DDU yard but swing in a loop south of DDU with a multimodal terminal at Jeonathpur on the outskirts where road NH7, barge traffic Ganga barge terminal Varanasi on IW-1 and IR and DFC all come together.

I LOVED the ceremony preceding the loco startup . So connected to the culture of the land. It’s best that they get to inaugurate it themselves because they worked to build it .

The final year figures are in. In 2020-2021 IR has electrified 6015 km of track a new record. Now 71% of the track is electrified on IR. WCR( in the heart of the IR network at the cross roads East West and North South) has achieved full electrification and is the second zone after ER to achieve 100% electrification. Zones like SWR which had 2% electrification at the start of NDA era are now at 39% electrification. Target for full electrification system wide is 2023. 45,881 km is under wires. Total rkm is 64,689 km. Last fiscal year 5,276km was electrified.

All of Konkan railway will be soon under wires maybe by June or July.

Italy 71% electrified: total network 16,723 km

Russia 50% electrified: total network 85,500 km

SNCF France 55% electrified: total network 28, 521 km

UK 38%: total network 15,915 km

China 72%: total network 139,000 km (2019 figures)

Japan 69%: Total network 23,956 km

Two maintenance sheds at Kanpur. Which one do you like? :rotfl:


The older Electric loco maintenance shed, the avatar of the steam loco shed Kanpur of my young days:

https://youtu.be/uv56lFBsASQ

The recently opened ( a few weeks ago) MEMU Kanpur maintenance shed. This shed services all NCR MEMUs and obviates the need of NCR MEMU's to go to Ghaziabad MEMU shed of NR for POH and maintenance and also some of NER MEMUs will be maintained here once NER gets more electrified and runs MEMU services.


https://www.youtube.com/watch?v=_1OTcDlR098

They was some panga with COD Kanpur(Central Ordinance Depot) on GT road with land issues for the MEMU shed. Got resolved. Old Mr. Heplett was bandmaster of the COD band in the 1960s before he moved to Australia.

First section of Konkan railways to be electrified and commissioned April 4th, Roha to Ratnagiri. Karwar to Mangalore(Thokur) loco trials are taking place. Ratnagiri to Karwar work is still going on in a few places. By June all of Konkan railways will be under wires. I suppose they could not make it in 2020-2021 year.

https://twitter.com/i/web/status/1378628390383542273

Total length 740 km. Commissioned distance 209 km.
