a mil grade GPS can also be easily integrated into the roof of each loco. even Meru cabs has them. cost is around 80,000 I heard.

Frankly, I don't have a problem with majority foreign holding of a non-critical area like a single high end locomotive manufacturing yard. They only make a limited flight of niche ultra high power engines. A high FDI margin in this particular deal enables them to more willingly transfer the high end traction technology to us. IRCON is pretty good at absorbing and indigenizing technology in this manner.

12000hp engines are quite a big deal. Those commonplace IR WDM2 Alco diesel locos we've all seen are a mere 2700-3100hp, a quarter of the power of these monsters. This is a deal to make something twice as powerful as the most capable locomotives in IR's fleet today. 800 of such powerful engines can do quite a lot for increasing IR's freight and passenger traffic throughput. Further, unlike FII, they can't simply withdraw their investment via an electronic funds transfer, because their investment is a large fixed asset nailed down to the ground.

More than 12000 hp locos, this is the need of the hour. Though Texmaco and Titagarh claim on their websites that their BOX-N and BLC ( open on all sides for containers say)wagons can go at 100kph, I very much doubt that. 12000 hp can of course pull larger rakes, but the number of wagons in a rake are constrained by how many can fit into a loop line at a small station both on single track and double track operations esp. when overtaken by a faster train. Currently a single WDP-4 can start a 60 wagon rake fully loaded on a 1:200 incline. WDM-2 production has stopped and only retro-fitting to WDM3 standards if at all goes on for some older WDM2's. The main point is to increase the speed of the wagons and have an efficient system to keep track of each and every wagon in the system by a system of laser readers or something similar to automatic toll collection. This information should be routed through a computer that handles all the logistics on wagon movements in an efficient way.

WAP7 locos can use the power pulled from the overhead wires to drive the AC in all coaches and so there is no need for a generator car for WAP 7 driven rakes to drive AC. The power drawn from the overhead wires also powers the ranges in the pantry car and is used for production of hot water. One reason given for not having AC in cabs besides drivers will snooze( same story for tanks not being fitted with AC by the Army!!) was that the AC unit needed to be run on diesel separately and was wasteful, hopefully WAP 7 models address this ergonomic feature. This feature of WAP7 locos is called HOG, or Head on Generation.

This is the current technology used by some small company in Munger(Monghyr) in Bihar to make BLC wagons, so...

http://indianexpress.com/article/india/ ... -a-minute/

Your chances of securing confirmed train tickets on popular routes just went up. The Railways has zeroed in on the biggest reason behind the perennial complaint of passengers not being able to get confirmed tickets even after turning up at the ticket counters at 8 am, when they open across India.

An internal investigation revealed that every day, 4,000 confirmed berths would be hoarded by touts within one minute of the computer reservation system being thrown open to public.

The probe found that the touts, who sell tickets at a higher price to passengers in need, were exploiting a “facility” in the passenger reservation software. The facility allows someone who has already purchased a ticket to alter journey details and book another train within seconds at the last moment.

Touts would buy tickets for relatively less popular trains a day earlier, and then swap them for tickets on popular trains — Rajdhanis, Durontos and other long-distance trains — between 8 am and 8.01 am. This would take seconds since their booking details were already fed into the system.

“Touts would buy any ticket a day in advance and the next day, they would get ticket details changed. The booking clerk merely had to generate another PNR with the passenger details already fed into the system a day earlier. This took seconds,” Ajay Shukla, Member (Traffic), Railway Board, told The Indian Express. “We have now disabled this facility for the first hour after the system opens,” he added.

The probe, launched after the Railways Ministry found a huge number of tickets being booked this way, also indicated that booking clerks and other insiders were involved in the racket. The ministry plans now plans to pinpoint the culprits and take action.

The BJP govt under Modi is doing a wonderful job. They did things in 10 months what UPA could not do it in 10 years.

Okay. But for this system, the touts would have to buy a ticket with the same passenger details, who requires the Tatkal ticket the next day. Because other wise mere generation of ticket with some incorrect names would not be possible. The passengers would get caught when the board the train.

Good that the glitch was identified and rectified. But a few of the conniving booking clerks, suspended and enquiry initiated against them with a dismissal (with all perks nullified) would also bring back the erring sheep back to the fold.

Those touts exist because there are not enough seats on trains.

per my understanding the WDM and WDP series of diesel locos are diesel-electric and use traction motors, so a massive amt of electricity is being fed into these motors, what is the problem with running a small 0.5t AC for cab cooling?

and it should be no problem in any of the electric locos, whether or not they supply to entire train, they are getting a meaty electric feed into the loco itself.

As I said Railways think it does not save fuel, check this from the IRFCA site on WDP-4 and Hubli division.

http://www.irfca.org/faq/faq-loco2d.html

Unusually for IR locos, the DLW-built WDP-4's have cab air-conditioning factory-installed. However, the Hubli shed apparently discourages the use of the air-conditioning equipment for fear it affects fuel consumption adversely [10/04].

1. Hubli shed is one of two sheds that houses the WDP-4 so if the factoid on IRFCA says Hubli shed then pretty much that is the situation for all India. You can see these hardworking EMD types a lot nowadays, just travel by Hampi express and you will see many at Guntakal, Hospet and if not your train Hampi exp. will be hauled by a WDP-4.

2. To illustrate a classic case of HP, take a look at this video. It shows Karnataka express double hauled by two WDG-4, of similar type as WDP-4. As the title says, 9000hp, and the videographer proudly claims that they caught the train 3 times by travelling on a bike( I hope not a bicycle). A whole host of people congratulate the videographers. The train at most places moves quite slowly. The videographers show you how they managed to catch the train 3 times by displaying a map of their bike route and the train route. The problem is when tracks were laid in the old days, builders frequently went around ghats, minor hills and so on and this made for many curves, good for pictures but of no use for even moderate speeds even when coupled to 9000 hp of motive power. All that has to wait for massive though moderate straightening of tracks and in the case of Karnataka express that and double lining Bangalore-Hyderabad, which is not only not electrified but worse not double lined. They electrified it to Gauribidanur and stopped, quite meanigless really. It has long exceeded capacity of being single lined.

why is this fairly nondescript train hauled by two giant locos?

agree about the Hyd line. there is place on northern outskirt of blr called makalidurga which clearly shows the low speed curve thing again. ok for 1850s steam engines but no more.

May be due to gradient involved in the Deccan. It's still a 24-bogie train, and WDM-2s are not particularly powerful, at just 2600hp max . The most powerful diesel electric locos in active service are the WDP4s @ 4000hp . The two new locomotive sheds will build far more powerful 5000hp diesels and of course the 12000hp electric locomotives.

it is not a glitch but a backdoor/window purposely left open during the software build process so that it can be exploited. Such "fortuitous" software glitches are never mere happenstance. This is just like all central and state welfare schemes that have a purpose built loophole that is then used quietly by the party in power to drain the scheme before the moneys actually reach the beneficiaries. This is how the cadres are "kept happy".

my video seems to have the same karnataka express hauled by a lone WDM loco up into the bangalore plateau. ofcourse the gradients might be more further up north across the vindhyas.

That is a standard practise. At Castle Rock (border station of Karnataka) there are one set of Gooty (GY) shed locos who are just kept their for these kind of duties. When a train goes down hill, twin-locos get attached to the front of the existing loco as "brakers". They slowly pull the rake down the ghat and at Kulem (in Goa), the twin locos gets shunted out. They wait there for the next train going up hill, and get attached at the rear to form the "bankers". They help the lead loco, by pushing the rake from the back.

Dehradun - Varanasi Janta Express derails at Bachhrawan(scheduled stop) near Lucknow. 30 dead, 150 injured till now. According to preliminary reports, the locomotive driver apparently overshot the signal and as a result, the engine and two adjoining coaches derailed, railway spokesperson Anil Saxena said in Delhi. Most probably the brakes failed.

LHB coaches surely would not have been in this condition.

We cannot speculate on the brake failure part, and need to wait for the official enquiry reports. The signals in railways just do not turn up red all of a sudden, the driver would have received advance warning (through the distant signal) that the signal ahead is red. He ideally would have started slowing down, and would have known that some thing is wrong.

During the initial investigation of the Ernakulam-Bangalore Intercity near Anekal Road, there were rumours that the engine driver was at fault. And that he was over speeding. Finally it was pretty much concluded that the track maintenance team had worked on that part the previous day, but did not keep a caution order for the next 1-2 days asking trains to reduce speed in that area.

Pvt players may run freight, passenger trains
A high-powered panel constituted by the Centre to reform Indian Railways is likely to recommend entry of private players in running freight as well as passenger trains, producing rolling stock such as coaches, wagons & locomotives and developing rail land.

The committee, sources said, could also suggest setting up a regulator - independent of the railway ministry as well as the Railway Board - to manage track access, among other things, after private players were allowed to run freight and passenger trains.

All matters related to tracks, including infrastructure, the report is likely to suggest, be owned by a holding corporation independent of Indian Railways.

The committee is also likely to recommend Railway Protection Force (RPF), schools and hospitals for its staff cease to be under the direct control of Indian Railways. Indian Railways runs a network of hospitals and schools for its employees.

"What could be done instead is that the railways hire personnel for security of its assets from RPF, while schools be handled by Kendriya Vidyalaya Sangathan and hospitals integrated with the Central Government Health Scheme," the official said.

The committee is also expected to recommend Kolkata Metro Rail Corporation, brought under the fold of Indian Railways during the current tenure of West Bengal Chief Minister Mamata Banerjee, be detached from it.

On suburban trains, the committee, officials said, might recommended all unviable lines be run under a joint venture with the states concerned, starting with the Mumbai suburban railway.

Debroy panel for complete switching of Railway tracks

Sources said the committee is likely to suggest coming out with an upfront passenger fare subsidy — this was Rs 34,928 crore in FY15 — and getting both the Central and state governments to pay for this as they do for the annual electricity subsidy for agriculture right now. While the Centre will pay for all Central railway lines, states like Maharashtra will pay for suburban train networks.

Subsidised tickets, the committee is of the view, must be linked to Aadhaar IDs, in keeping with the government’s overall philosophy on cutting leakages on subsidies. The Economic Survey had pointed out that the bottom 80 per cent of households comprised only 28.1 per cent of the total passenger traffic on the railways, making it clear that it is not the poor who get subsidised.

In addition, since private firms cannot run trains right now as the tracks and signalling are controlled by the railways, the committee has suggested this be transferred to an independent entity and, with a railway regulator in place, allow private firms to run both passenger and freight trains.

A person associated with the report said there would be no annual presentation of the Railway Budget and talk of dividend and gross budgetary support — the Union Budget, he said, will only mention the social obligation that will be borne by the Centre.

The committee has also suggested greater private entry into production of coaches and locomotives. All the production units in the railways would be made completely independent by turning them into holding companies. Rationalisation of zones and divisions; decentralisation of power to GM and DRMs; complete switch to commercial accounting for all the railway functions; and delinking of RPF, hospitals and schools are among the other steps outlined by the committee.

The Railway Board’s role in the whole scheme will be limited to what is actually run by the railways and HR functions will also be revamped.

Sachin ji,

http://timesofindia.indiatimes.com/city ... 640626.cms

Quick action by the driver and the guard of the ill-fated Janta Express, as well as the cabin staff at Bachhravan railway station, may have prevented a bigger tragedy on Friday saving hundreds of lives. Recalling the tragic turn of events, guard SK Mishra on the Ganga-Gomti Express (Lucknow-Allahabad) said, "The driver realised the brakes had failed near Nigohan. After I was informed, the Bachhravan cabin got into the act and diverted the train into a loop line," the technical term for a concurrent track for precisely such exigencies.Mishra said the Bachhravan-Rae Bareli section is single line, and the driver of Janta Express wanted a clear line so as to slow down the train over a period of time.

"However, at 9.10am Ganga-Gomti Express, too, was in the outer area of Bachhravan, and if the speeding Janta Express (at 80-90 km/hour) had not been diverted to the loop line, the casualty figures would have run into hundreds," Mishra said. The coaches behind the engine telescoped into each other from the impact of the derailment.

Mubbasir Khan, 30, in the S-5 compartment, said, "When the train crossed Nigohan station, we felt it jump. It must have been doing 80-90 km/hour. We fell off our seats when the guard applied emergency brakes. Ganga-Gomti was almost 10 km away from the accident spot. I saw several bodies lying and consider myself fortunate to have survived."

Similar accounts were narrated by 41-year-old Ram Dhani, a resident of Ghazipur, who was returning to Varanasi from Dehradun along with his relatives Bhagini Devi and Ramesh Kumar.PAC sub-inspector Rajesh Kumar Upadhyay, who arrived in Lucknow by Ganga-Gomti Express, said, "The images will haunt me forever." He helped policemen and villagers pull out bodies from the debris saying he feared the casualties would go up.

12 international companies look to be part of bullet train project

http://www.business-standard.com/articl ... 076_1.html
Reputed companies from six countries, including France, Germany, Italy and China, have entered the race to become part of Prime Minister Narendra Modi's pet Diamond Quadrilateral bullet train project.

Twelve international companies are bidding for conducting the feasibility study for the three corridors of the Diamond Quadrilateral high-speed rail network project, said a senior Railway Ministry official.

Feasibility study is being sought for high-speed rail corridors between Delhi and Mumbai, Mumbai and Chennai, and New Delhi and Kolkata, which are part of the Diamond Quadrilateral project.

Four companies from China, including Siyuan, DB International from Germany, Systra from France, Sener from Spain and Italser from Italy, besides one from Belgium, have joined the global competitive bidding to bag the survey contract.

However, the official said that one company will be allowed to do the survey for one corridor only in the Diamond Quadrilateral project.

The bidding was opened this week and the winners will be decided within four months by July, said the official, adding that the feasibility study for the three routes is estimated to cost about Rs 30 crore.

The steepest slopes on a trunk line is Thull Ghat on the Central Railway, Mumbai CST to Delhi via Bhusawal. Thull Ghat is between Kasara( last stop on the Mumbai suburban network) and Igatpuri. The slope is 1:37. Caution This means sine x and not the usual calculus dy/dx=tan x. That is if you move 37 metres on the hypotenuse you climb up or down 1 meter. This entire section was electrified maybe 70 years ago with 1000hp DC traction, which ended at Igatpuri where steam from Bhusawal shed took over. Now everything is electrified all the way to Delhi and DC has been converted to AC. WAG5 act as bankers from Kasara or Igatpuri. You can see videos of diesel WDP-4 pulling loaded LPG rakes with 3 electric bankers on this section and the great thing is the section is triple lined.

In the Satpuras and the Seoni hills( yes there is such a thing where Mowgli lives) and the Mahadev hills is also a steep ghat section on the Chennai-Delhi trunk line. A short ghat section between Teegaon and Chichonda of 17km,
Chichonda is 115 km towards Delhi from Nagpur. Bankers are attached at Teegaon and Chichonda. There is another stretch of 15km with tunnels and viaducts from Dharakoh to Maramjhiri with bankers waiting at both ends. Slopes here are 1:60. This is a double lined and electrified section with 250 train movements every day.
There are photos of tunnels with markers indicating 1:70 slope inside the tunnel.

It is mandatory for all trains to have bankers here too. WAP4 and WAP7 can easily pull the 26 coach rakes, but the railways fear that there is a possibility the first coupling of the rake to the loco can break with catastrophic consequences. To lighten the tension on the first coupler and the ones following to a lesser degree the bankers help in reducing the tension. WAG5 bankers are used in this section too.
Eventually strengthening of coupling devices should be addressed if one is to have single powerful locos pull the rakes all the way. It may not be worthwhile so bankers are as good for a large number of trains.
The tunnels on the downline from Delhi to Chennai that bear the inscription 1966 were all built by RJ Shah and company. My dad had a hand and so were the twin diversion tunnels ( also containing the penstock)of the Ramganga dam, Kalgarh, Corbett National Park( circa 1970) and Giri Bata project, Nahan HP tunnels for the dam and powerhouse penstocks. The tunnels were built at great cost as Himalayan geology was understood poorly and the geotechnical surveys cursory and done from the surface with many surprises as the tunneling proceeded.
The sliderule of dad bought Dec 1 , 1951 remains with me on my desk with an inscription inside the leather flap, it is my touchstone and provides continuity with what he did so well and what I can do perhaps not too well today.
After all he and others went on to found Industrial engineering in India in the 1940's too but that is another story.
Some pictures on Dharakoh Maramjhiri section, the station is as I remember it:

http://www.irfca.org/gallery/Trips/cent ... adventure/

http://dharakhoh.blogspot.com/2006/02/dharakhoh.html

As a trivia, on that section in Central India, traveling from Delhi to Chennai one first comes to Dharakoh and bankers to Maramjhiri and then Betul and following that Amla Jn. This Amla is a made up name. Ammunition was stored there and still stored there by the IAF. Amla simply stands for Ammunition land.
Another such made up name is Neemuch, or Nimuch, Northern Indian Mounted and Cavalry HQ. There is also the famous Babina near Jhansi on the Mumbai Delhi and Delhi Chennai trunk line. That is British Army Base in Northern Area. This is where some of the joint Yudh Abhyas exercises with the US were held.

Off trunk lines, some of the steepest slopes are on the Nilgiri Railway with 1:12.

It is in there -

Besides, a feasibility study is in progress by the Japan International Cooperation Agency (JICA) for the 534-km-long Mumbai-Ahmedabad high speed corridor project, which is estimated to cost Rs 63,180 crore.

Yes, I read that report. And yes this was an accident, but I guess a smaller one when compared to what were the other possibility - two trains hitting head on. I did read that the drivers, guard and the SM acted in unison, communicated through their VHF sets and took all the steps based on the SOP. But one thing I still cannot figure out, is how the brakes failed. For that we need to wait for the enquiry reports.

I had made a trip around 8 months back precisely for this reason :). But the rainy seasons over, the falls were not in its full glory. I had also made a journey on the same route during 1996 - when the line was metre gauge. The train had halted near the Dudhsagar water fall, but I could not figure it out then. I was proceeding to an NCC camp in Goa.

Yes. That is now pretty much a standard issue. How ever the walkie talkies operate on the VHF, and they have problems when communicating from inside tunnels etc. The IR had a much more cruder system in place, messages passed by blasting the horn in a specific order. The drivers used this to communicate as well. And with experience the driver (at the bankers) are also able to predict the movements of the leading engine driver, by observing the reduction/increase in speed and also the reading of the gauges/metres.

But will it not bring FDI and create more jobs?
