At this point there is no choice but to start looking at these as terrorism related. When will MSM start discussing this possibility openly with the word islam?

the bogies and underlying chassis of ICF coaches look to be very heavy duty ... perhaps the quality of track not being tfta also exerts greater shock and vibration vs the french TGV std tracks or some of the improved tracks like delhi-mumbai and delhi-agra ?

part of technical progress is shaving off weight and using lighter materials were we can.

With Russia’s help, India to increase train speed to 200 kmph

http://www.thehindu.com/news/national/W ... epage=true

Currently, the fastest train in the country is Gatimaan Express with a top speed of 160 km per hour

The Russian Railways is helping India’s national transporter increase the speed of its passenger trains up to 200 km per hour.

The Russian Railways is at present collaborating with the Indian Railways on a 575-km stretch between Nagpur and Secunderabad and submitted a preliminary report last week.

To reach the desired speed limit, Russian Railways has proposed several technical and technological solutions, including reconstruction of railway alignment as well as treating the earth bed where there are speed restrictions.

New passenger cars

Since Indian Railways doesn’t have coaches that can move with a speed of 200 km per hour, a new type of passenger cars needs to be approved as well.

It has, however, expressed concern over “a number of large bridges with speed limits” on this particular stretch and has recommended a detailed survey of all these structures on the basis of which measures for reconstruction/repair will be taken up.

It has also been pointed out that railroad switches, which enable trains to shift from one track to another, at stations on this stretch are not suitable for a speed of 200 km per hour and a different type of switch has been recommended.

Digital tech network

A digital technological communication network for the entire section, instead of the existing radio communication, was also proposed.

A high-speed rail network will also require safety measures for pedestrians and motor vehicles at rail crossings.

Keeping this in mind, overpasses, anti-collision and anti-ram barriers as well as automatic alarm systems have been suggested.

A protective fencing along the length of the rail track was mooted in order to prevent accidents with people and animals on the track.

The Russian Railways also suggested noise shields for tracks near residential areas.

A protocol for this project was signed between the railway ministries of the two countries in October last year.

50:50 cost sharing


The high-speed project will be jointly financed and the cost will be split equally between the two countries.

Currently, the fastest train in India is Gatimaan Express with top speed of 160 km per hour.

It seems like each stretch is being "studied" by a different country. Talgo Trains with Spain, Mysore-BLR-Chennai was done with China (I read now another consultation with Germany might be in the works), the above with Russia. Again too many committees...very little action.

"Swanky" Five Star hotels on top of railway stations that might have Diesel Engine and/or open toilet trains? Not exactly something to look forward to. If someone has a vision similar to London St. Pancras, a HSR station might be a better fit.

However, I am all for converting old heritage buildings such as CST and Chennai Central into museums and replacing them with ultramodern green buildings away from city centers. Those ultramodern buildings can be multistorey and house shopping, food courts and traveller lounges of all classes. Sleep and shower facilities would also be great. One thing that would be great is to design stations such that platform ticket enforcement becomes more efficient.

there is no way to retrofit modern railway concourses like these onto any RS in india , big or small. this will have to be greenfield on outskirts.
all the "studies" will find the same issues and same remedies. GOI has dangled some carrots like trainset orders for semi-HSR maybe to get these free studies done...but I believe main thing is funding for the huge track, fencing, underpass and bridge improvements needed over 1000s of km - trainset is the smallest of problem but grabs biggest eyeballs and media hype.

I think both diesel engines and train toilets are being taken care off. They are putting bio-toilets and vigorously doing electrification work. However, after leaving a swanky station you may encounter a series of slums with people doing potty next to tracks. At least that is my experience in Delhi and to a lesser extent in Kolkata. These are mostly encroached land. They need to do something about these. Otherwise, the poor quality of railway experience will remain. In my recent travels I hardly found any foreign tourists in trains. This was not the case even in the 90s when air-travel in India was not that easy. Now majority of tourists have moved to airlines unless there is no alternative.

MP talks about a Goa metro

It would be lovely if Goa gets a metro. However, what's the feasibility ?

Goa has a wide population spread between tourist season and off season.

Due to The new airport at MOPA, Mapusa will become the most important city in Goa.

From Panaji, I suspect the alignment will run North to Mapusa and then where ?the tourist trail Calangute-Baga-Anjuna-Arambol or maybe it makes sense to link Mapusa with the new airport.

For a state, whose taxi mafia have, so far, successfully, prevented Uber and Ola from operating, it will be interesting to see how MP will deal with this lumpen lot.

Any why is MP making these announcements instead of LP?

Are Goan cities big enough to have Metro or should they have a RRTS? Never been to Goa but it looks like urban state with lots of small cities and towns. A RRTS seems ideal for it.

An old video from SHQ: 9x JNR EF65s (100ton, 3500hp electric locos built by Kawasaki/Toshiba/Nippon Sharyo) with a combined weight of 1000 tons, run the route through the Seto Ohashi - the worlds longest series of double decker bridges - in 1988 before its inauguration. Great views of the track and bridge flex from the weight.

Talking about Shinkansen, here's the early prototype being tested on the Tokaido line in 1959-60:
https://www.youtube.com/watch?v=PK0-_gQpnaI

Back then, they didn't look a whole lot different from us, just rebuilding after being bombed to bits. All the huts off the tracks looks curiously similar to what you'd see out of an IR train, except this one's going a lot faster...

With recent train derailments in context, and railways allocating a significant part of its budget for safety, here is a solution that might work,

Taking the self driving cars with tube less tires and putting them on rail tracks so that they travel ahead of the trains at distances (less than a 1km) that allow for emergency braking of the train should this pilot vehicle hit an obstacle, derail or detect a hazard. The pilot vehicle has live CCTV feed looking ahead as well as at the tracks for issues, the CCTV feed is sent to the locomotive over a two way RF link. Image processing software can flag hazards in real time for the train crew to act on. Its sensors should work in night and foggy conditions as well.

It would also have a "red lamp" on top, something that is suitable for Indian environment. if a fire engine is approaching we can hear from enough distance.

This pilot vehicle is synced to the speed of the train increasing or decreasing the distance to enable safe braking of the train. Most of us trip on the safety aspect of such an arrangement. if the RF link fails the driver stops the train reducing the chance of the train hitting the pilot vehicle. Alternate communication nodes are setup along the tracks if the RF link is prone to disruption due to natural obstructions such as hilly terrain or tunnels. Without going into the "design" too much, these are some of the expected characteristics, the vehicle ought to be light weight so its acceleration is comparable to that of a motorbike with a truck and in the remote case of the train hitting it, its pushed out of the way. FRP can be used for the vehicle body. The vehicle can step aside the tracks using its own power also useful during train shunting operations.

They should have enough endurance to travel non-stop maybe equipped with 2 engines switching every few hours. To maintain their reliability should be replaced within few years of service. At 11000 trains on the rail network, a fleet of 15000 or so can be used which is typical of the operations of a big car rental company. Railways should really outsource such work and the sensors themselves should be outsourced to technology partners.

On self driving cars,
https://www.indianagazette.com/news/reg-national-world/selfdriving-car-prototypes-need-less-human-help-data-show,25819398/
The scenarios faced on a contained system like rail tracks is less than that of traveling on roads so the rate of false alarms is low.

Maybe it should be revived with newer technology providing better options. The railway track itself needs continuous monitoring, last year a low lying area was flooded and the tracks washed away causing a derailment in the night, then there are the Elephants getting hit incidents.

This pilot vehicle based on regular cars is a quicker way to get on the tracks, however if a FRP based vehicle is considered then they could make the left side and right side sections including the axles joined over pyro bolts so a trigger causes it to split into two parts pushing them to the sides of the tracks. The trigger could be a G-shock or a laser range finder and a rear camera measuring the approaching train.

in comms networks there are ways to monitor and locate breaks in the line , whether via wireless devices that penetrate the earth or inbuilt out of band monitoring. perhaps similar ideas could suffice with a wired network buried in parallel near the tracks and pulling sensor data for onward processing in unmanned nodes, with feed upstream into sectional station masters. sensors to detect earth movements, vibrations caused by explositions, track breaks (pass a small current through sections and monitor for break?)

a fitting case for large scale IoT methinks. I am sure some variant of this is already used in the HSR lines worldwide...a single break there is a disaster rather than a moderate derailment due to the high speed. we saw what happened in the Cheen hsr crash on a bridge.

These kind of systems do exist. The "pass a small current", scheme is what is known as "track circuiting" in Railway terms. Small currents are passed onto the tracks. These tracks are also split into sections (by placing a non-conducting material between the tracks, when they are joined). When a train (or any vehicle) moves on the tracks it is actually "short circuiting" the "track circuit". And this is how the signalling system "detects" that there is a train on that section. And based on that the "signal panel" on the station master's room actually tracks the movement of the train in his territory.

But the track circuiting may not be there in many areas where the gaps between stations are really wide. Here from a signalling perspective, track circuiting is not necessary as signals etc. are only closer to the railway stations. But may be they should do that, in order to track defects on the tracks. Other wise the current way is to do routine manual patrolling (by the gang men, who have a specific "beat" to cover be it night or day).

These track circuits also helps in "Automatic Block System" (ABS) in busy sections (for eg: Mumbai & Chennai suburban system), where the train's own movement controls the signals on the rear of it. In Konkan Railway they had also come up with some metalic wire meshes, and used some how grown electric circuitry to detect if the wire mesh is broken. These wire meshes were placed next to the rocks etc, which was crash prone. A land slide would be detected by these wire meshes and alerts would flash to the stations, section controllers etc.

Railways to show green signal to a train in Andaman and Nicobar

A 240-KM broad-gauge railway line connecting two major islands, with bridges and stations along the coast, will be part of an ambitious rail link connecting Port Blair with Diglipur on the Andaman and Nicobar Islands — a first in the country that will bring the archipelago on the rail map.

The Railway Ministry is set to approve the project, which will connect the Union Territory’s capital city in the south with the largest town on the north Andaman island currently linked by a 350-km bus service that takes over 14 hours and a ship that takes around 24 hours. There is no air connectivity.

According to an internal survey report of the ministry, the cost of the line will be Rs 2,413.68 crore with a negative rate of return on investment of -9.64 per cent. The Railways considers a line to be commercially viable if this figure is at least a positive of 12 per cent. But the ministry is set to approve this project owing to its “uniqueness and strategic importance”, according to documents reviewed by The Indian Express.

The ministry’s Planning and Finance directorates cleared the project last week saying it is desirable because “it is unique, away from the mainland, and has tourism potential.”

Giving a fillip to the rail link, the Union Territory administration has agreed to share 50 per cent of the project’s operational cost — or loss.

“As soon as the line is commissioned, tourism will see a jump from the current 4.5 lakh visitors a year to around 6 lakh a year, as per our estimates. So even though the railway survey shows a negative return, our assessment is otherwise. However, we have agreed to share the operational losses, if any,” Jagdish Mukhi, Lieutenant Governor of Andaman and Nicobar Islands, told The Indian Express.

According to the UT administration, the line has tourism potential and is of “immense strategic value” to the defence forces because Diglipur is just 300 km by sea from the southern coast of Myanmar — a broad-gauge train line from Port Blair to Diglipur will take three hours at the most.

The Railways’ Planning wing has suggested that the project may be taken up as part of the strategic lines it will build for Defence ministry, such as those in the border regions of the Northeast. The Finance arm has said that it may be taken up as a national project, like the Kashmir link, in which the general exchequer is billed. The Railway Board will take a final view on this issue soon.

The initial survey for the proposed line was completed in December 2014 but the plan was dropped. Last year, the project received a fresh push when the Railways updated the survey and the UT administration said it would chip in.

Among the major tourist attractions in Diglipur are the Ross and Smith islands. “These are just two of the main attractions. Lakhs of tourists take great pains to reach there from Port Blair every year. With the railway line in place, that part essentially become a part of the capital, beneficial to tourists, local residents and the defence forces,” said Mukhi.

In a recent incident, they put a section of the rail across the tracks and the contact points with the track were insulated to avoid the "shorted" circuit alert message. Their idea might be to dovetail into the "derailment noise" of railways which is high.

In any case, if we see terrorism has a spill over effect whenever surgical strikes happen or in the run upto the Republic day etc., more active measures are needed.

Railways, if and when, are at a lower alert level can engage such unmanned vehicles for maintenance activities such as the thermite welding of the track joints during non peak hours. Daksh RoV comes to mind.

looking at videos, the andamans are surprisingly large around 300km N-S main island and has one road along the spine with hardly any spurs off it. this road seems like 1.5 lanes wide and at level below a state highway in the mainland. so even 300km is a 15hr journey by bus.

if they can 4 lane this road on the existing alignment , not only would it avoid environmental issues but also help people all along the way rather than a new alignment for railway.

Looks like the recent spate of train accidents do have a "terrorist" angle to it.
Kanpur train accident: prime suspect arrested in Nepal
One of the key suspects in connection with the derailment of Indore-Patna Express in Kanpur was arrested at Tribhuvan International Airport on Tuesday after being deported from Dubai.

A special team of Nepal Police arrested Samshul Hoda and three others.

---
Looks like this was a well coordinated plan by three police agencies (Indian, Dubai & Nepal). The scoundrel was first deported from Dubai (I am sure MEA had played an active role here), and Nepal police was waiting for him to set foot in Nepal. Earlier even this news may only come out, after Mr. Shamsul Hooda was found loitering suspiciously at a bus stand in Indo-Nepal border, and the beat constables arrested him".

I am remembering my grandpa repeated sayings about M Visvesvaraya. He used to say V is a great engineering mind. Once he pulled the chain and said, don't proceed over the approaching bridge. On questioning, he said the sound waves that hit his ears shows a clear sign of fracture in the bridge. They laughed at him.. He got down along with many. Many others died on the bridge collapse as the coaches slowly moved over it.

T/F or Urban Legend?

I think it is important to use ultra/-sonics and sensors on the run/real-time analysis and provide feedback. possibility? all depends on our designs. data collection is important to learn the abnormal deviations

Even for the IoT, if sensors are placed say at the wheel-set level, all that generated data could be transferred to the pilot vehicle which could play a mobile tower and then be connected to trunk networks via satcom. This also provides net access to all the passengers as the rake is within the pilot mounted mobile tower range. Railways can then charge for the net access or make it a perk on higher fare tickets like airlines do.

so they could be recuperating their costs and give some meaning to the insurance cover they provide

NEW DELHI: The railways will use LiDAR technology — which involves conducting an aerial survey, and is known to give accurate data on the contours of land, even below vegetation — to expedite work on India's first high-speed train corridor between Mumbai and Ahmedabad.
The use of Light Detection and Ranging, or LiDAR, will allow the survey of the 508km corridor to be completed in 9-10 weeks against the normal 6-8 months.
It will help the national transporter start ground work on the Modi government's dream project by 2018.
According to the plan, almost the entire corridor will be on an elevated track, except 21km that will be underground. Of the 21km, 7km will be undersea.
The survey will be conducted by a helicopter, which carries equipment, including a high-resolution digital camera (100 megapixel), a laser scanner and a data recorder.
An official said LiDAR was a remote-sensing technology that measured distance by illuminating a target with a laser and analysing the reflected light. The GPS unit interacts with GPS satellites to finalise the ground control points.
"The total flying time for covering the full corridor will be 30 hours. The preparatory work and time taken in processing of data is quite high, but still the process allows the survey of the full 508km in 9-10 weeks instead of 6-8 months," Mukul Mathur, executive director (PPP), railway board, said. The exercise is highly accurate and enables capturing data of buildings and forest," Mathur said, adding that this technology would be used for the survey of a rail line for the first time. For the survey, the helicopter will fly at a height of 500 metres while identifying 15.6 points per square metre.
As the survey generates very accurate data, the permission of the defence ministry and the DGCA will be sought, an official said .
The LiDAR survey is among four surveys —geo-technical investigation, hydrological survey and land plan preparations — being conducted by RITES at a cost of Rs 40 crore to finalise the alignment of the corridor.
Nearly 81% of the funding for the project, estimated to cost Rs 97,636 crore, will come by way of a loan from Japan.

This is great. Just compare the two links below to get an idea of the difference between helicopter borne LiDAR and satellite imaging. The former is more informative about the landscape.

These things are not that expensive if used in large scale. I wonder why it needs a bullet train to justify the use of such techniques. If even a fraction of bullet train construction related tech, expertise and operating procedures trickle to IR in general, it will be a huge leap.

After 15 years, Bogibeel bridge in Upper Assam nears completion

Image

DIBRUGARH. FEBRUARY 13:
A series of pillars, mostly incomplete, running across the 4.94-km wide Brahmaputra... For long, this was was the picture at Bogibeel, near Dibrugarh in Upper Assam.

But this is now set to change.

The bridge is finally nearing completion and is expected to open rail and road connectivity between Bogibeel on the south bank of the Brahmaputra and Silapathar in Dhemaji district on the Assam-Arunachal Pradesh border, in a year.

And, for Prime Minister Narendra Modi, who will seek re-election in 2019, Bogibeel may serve as a concrete symbol of effort to develop infrastructure in the North-East, and also forbetter defence logistics along the Sino-Indian border.

India has 3,488-km-long land boundary with China. Almost a third of it runs in Arunachal Pradesh. Currently, the rail and road link to Arunachal is maintained by three lower- and mid-Assam bridges — Jogighopa in Bongaigaon district, Saraighat near Guwahati, and Kolia-Bhomora between Sonitpur and Nagaon.

But this means a cargo from Dibrugarh in the north-eastern corner of Assam takes a 600-km detour merely to cross the Brahmaputra.

The only other alternative is crossing by ferry. But that is not suitable for large and heavy cargo.

Moreover, in a region where the monsoon lasts six months (May-October), ferry services often remain disrupted for months.

Strategic project
To improve logistics along the Sino-Indian border, India had planned a number of infrastructure projects nearly two decades ago.

This includes the construction of a Trans-Arunachal Highway on the north bank of the Brahmaputra, and new road and rail links over the mighty river and its major tributaries such as the Dibang, the Lohit, the Subansiri and the Kameng.

Bogibeel was a central piece of this plan.

It aimed linking NH-52 at Dhameji with NH-52 B in Dibrugarh; convert the metre-gauge rail links in the north into broad gauge and connect it with existing broad-gauge rail link at Dibrugarh, creating a loop running across Upper and Lower Assam.

Though approved in 1996, construction of the bridge was initiated by the first BJP-led NDA government in 2002.

The Congress-led UPA government, which ruled for a decade since 2004, appreciated the importance of the bridge and declared it as a national project in 2007.

But implementation was slow, despite a Congress government in the State.

In July 2014, when this correspondent visited the project, 15 out of the 42 piers were coming up while work had barely begun on the rest.

The project cost had spiralled to ₹6,000 crore from ₹1,767 crore in 2002.

The scene has now changed dramatically.

The construction of the piers is complete. The superstructure is 70 per cent done, with 29 out of 39 steel spans, each 125-m long and weighing half a coal-laden cargo train, already resting on the piers.

The rest of the spans of the double-decker bridge will be in place by July.

Road building, on the upper deck, is apace at the Silapathar end. Laying of railway tracks will begin soon. Hindustan Construction Company (HCC) is confident of completing the bridge by March 2018.


Bogibeel is the most important, though not the only, proof of infrastructure push in the region.

The 9.15-km Dhola-Sadiya bridge at the confluence of the Lohit and the Brahmaputra further up at Tinsukia in Assam is also nearing completion.

Conceived in 2011, it was scheduled for completion in 2015.

Latest reports suggest the bridge, along with approach roads, will open early next year, offering easy connectivity to western Arunachal.

The Patkai range of hills running through Tinsukia and Dibrugarh are now hideouts of Naga and Assamese militants.

But the bridge, coupled with Stilwell Road that connects Tinsukia to China through Myanmar, will throw open more logistics options for the Army operations.

The Centre recently completed a second bridge at Saraighat and announced plans to build at least two more bridges over the Brahmaputra in Upper Assam between Bogibeel and Kolia-Bhomora.

The government has announced a ₹60,000-crore accelerated road building plan for the North-East, including widening of the national highways.


My take: Congress approved the project and declared it a national project. But nothing moved on the ground despite them being in power at both centre and state.

Sorry for the large pic.

I don't understand IR train designations anymore. Too many...too complex. We have

1. Regular Rajdhani Express
2. Regular Shatabdi Express
3. Jan Shatabdi Express
4. Duranto Express
5. Uday Trains (Double decker)
6. Tejas Coaches
7. Humsafar Coaches (?)

I wish they eliminate some of the above and standardize rakes.

I believe the pic confuses between Tejas and Antyodaya express. Antyodaya is similar to passenger trains in IR.

Gauge Conversion, on the historic Punalur-Sengottai route over the Western Ghats is nearing completion after 8 years.
This route was started by the Travancore Maharaja in 1903 from Kollam/Quilon to Shencottah/Sengottai as a Metre Gauge track. Tracks were dismantled in 2009 for GC, but nothing else happened. The famous Quilon mail from Chennai Egmore ran on these tracks. CRS inspection has taken place last two days from Punalur to Edaman in Kerala and Sengottai to New Aranyakavu partly in Tamil Nadu. Now 20kms remain to link up New Aranyakavu with Edaman. A new tunnel and a new viaduct are almost complete. The old MG tunnels had a conch symbol on the tunnel mouths. This was the symbol of the erstwhile Travancore kingdom. You can see that this symbol has been removed in the GConverted tunnels.

The old 13 arch viaduct has been jacketed to give it additional strength after gauge conversion.
Video is in Tamil, but since I speak, Tulu, Kannada, Kanpuriya Hindi( this one like a villager Dehati from Kanpur Dehaat), Tamil and Bengali no problem for me.
