Sirjee, land was an issue in case of bangalore metro. As usual, the IR muscled its way to the planning committee with its broad gauge proposal. But BMRC cited increased land acquisition and overall project cost to shoot down the proposal.Rahul M wrote:ravi IIRC it's for commonality with global standard. I don't think it's a land issue.

sridhar saar, new metro lines are being planned where they will share a node with vanilla IR lines. I haven't heard of this particular proposal. what are the advantages of it ?
I would definitely like to know more about the difference. More specifically how "standard" gauge will help.Rahul M wrote:what you are talking of are the local/suburban trains, all major cities have those may not be as well known as mumbai's but they are not any less crowded or important. . that's not what I'm calling metro. at the moment the difference in standard between the proposed/UC metros and these is too much to think of a common system. I'm guessing you do not have much experience of these sub-urban trains ?
the metros primarily cater to the intra-city transportation while the local/sub-urbans trains carry people to and from the city centre to the outskirts. while slowly the metros will expand towards the sub-urbs, they are still far way-off from replacing them. the difference between the two systems is almost as much as that between bullock-carts and motor cars.
The issue is complex.ravi_ku wrote:Any reason for choosing the various city metros phase to be western standard guage instead of Indian standard broad gauge?
Sreedharan wants to use all imported equipment. No attempt is made by DM to establish manufacturing in INDIA.
IT adds up to 153.56 million. That's the number of online train tickets sold since January 2002, when Indian Railways offered its passengers the option of booking a ticket on the Web.
No wonder then that when Google released its list of most searched items in India recently, along with giants such as Nokia, SBI, Sony, Samsung and BSNL, there was also this public sector unit called IRCTC — Indian Railways Catering and Tourism Corporation.
Another example in the urban, rail-based transportation system is the Delhi Metro's highly popular pre-paid, smart card. The popularity of smart card reflects the willingness of people to pay more upfront to avoid queues. For the financial year ended March 2010, on a daily basis, 54 per cent of Delhi Metro commuters — daily average of 4.91 lakh people — opted for smart cards to avoid queues.
Quite naturally, the desired way forward would be interoperable transportation smart cards — which can be used to make payments in buses, trains, metros, across cities. Countries such as Japan and Singapore have already taken initiatives in this direction.
In India, a project has already been launched to test such interoperable cards at Mumbai — for the BEST buses and Central Railways' local trains.
But, the report does not speak of any criminal proceedings aginst those who indulged in this.In the wake of growing complaints from the public regarding server inaccessibility when booking Tatkal tickets, the Indian Railway Catering and Tourism Corporation (IRCTC) has barred agents from availing this facility for an hour, when it opens at 8 a.m.
Tatkal booking opens two days ahead of departure, and a daily 15-minute server failure meant booking was hampered.
The allegation is that this was done to benefit the IRCTC agents, as one is forced to go through them to book Tatkal tickets, having to pay a heavy premium.
Within a matter of minutes, all the Tatkal tickets get booked, leaving the general public high and dry. Then the IRCTC website would start functioning normally all through the day. The railways sell about 9.5-lakh tickets for reserved berths of all categories each day, of which Tatkal accounts for 1.5-lakh tickets.
I have a doubt here. The whole logic behind the web site beginning to accept bookings at 8AM was to ensure that it coincided with the time when the manaul booking counters opened. Or else it would be unfair to the people who do not have internet connectivity. It is true that Tatkal booking using the IRCTC booking is pretty much a non-workable thing. May be lots of people (agents+others) logging in and crashing the servers. But blocking the site for one hour to the agents would not be a workable solution. The agents can still join the early morning queue, or have a tie up with the booking clerks and get the Tatkal reservation done.SSridhar wrote:But, the report does not speak of any criminal proceedings aginst those who indulged in this.
Compare the service, look and feel of IR with DM. Would you have preferred the IR??Theo_Fidel wrote:IIRC correctly, much of the SG/BG silliness is political. Looking at some of the history is valuable.
IR has project Unigauge which at great cost is standardizing to broad gauge lines w/ wider coaches.
Delhi Metro starts with a team taken largely from Konkan Railway.
Konakan Railway is staggering under an huge debt load and it looks like it will have to be rescued by IR.
IR is terrified that Delhi Metro too will go bankrupt and land on its neck.
Sridharan insists DM be standard gauge. IR refuses to pass safety inspection. Remember IR still thinks DM will land on its neck and also IR is being difficult.
Sreedharan wants to use all imported equipment. No attempt is made by DM to establish manufacturing in INDIA. This has now come back to bite DM in the butt with all the problems it is having sourcing coaches.
Isn't it tragic that after all that investment by DM for 15+ years we have no technology to build the equipment locally? No long term ability. No competitive advantage. This was Sreedharan's choice. Its one thing to try and fail, DM went out of its way to not try.
Even the contractors were foreign and they have now left and the quality is no longer the same because the locals were not brought up to those standards. What was DM thinking, one wonders.
Time may have been a big factor, but still...
IR wins first round and DM phase 1 is standard gauge. Sreedharan insists coaches be Standard gauge size eliminating broad gauge advantage. Yes playing with our money.
DM becomes 'profitable' and stays separate from IR so now has leverage to go to standard gauge and standard gauge size coaches.
The smaller coaches are already causing capacity issues and over crowding worse than it needs to be.
But who cares. Politics reigns supreme.
Standard Gauge is about 10% cheaper than Broad Gauge to build , but broad gauge can hold about 15% more passengers. (3.2m vs 3.66m width)
Railway sources said that the work would take at least a few months for the completion. It would enable the Southern Railway to operate goods trains on Pamban Bridge, which was recently converted into broad gauge.
Indeed, true. Indian PSU run operating system might not have that talking paperclip or provide us frequent mandatory updates in a prompt weekly fashion. Otherwise it will run quite well, like that butt-ugly Fortran based IR reservation system, that was architected back in the 80s. I never expereinced a double booking on that system, despite extreme geographical mismatches of booking centersRishirishi wrote: Compare the service, look and feel of IR with DM.

To handle peek hour load, frequency of the trains must be increased. Increasing the size of trains, means that you have to run larger trains, even during peak hour (more costly), larger trains also means more congestions on platforms and other infrastructure.
With SG DM can implement the latest tech worldwide. With BG DM would have been at the mercy of the junk IR runs on.
Indian PSU could probably make in operatig system for the computer, but would it be a good idea?. Much better to use Windows.

For at least 15 years, suburban trains in Mumbai have used an Auxillary Warning System (AWS), which prevents trains from jumping red signals. But even though there have been 43 major accidents in the past two decades, the railways are yet to install similar technology in all trains, which could save hundreds of lives.
nachiket, phase I completion was the crucial one, that proved things can work as planned and on time. For hitting that deadline without delay, he can import all he wants. But after that phase, Shree Shreedharan would have got anything he asked for, including some good ToT agreements.nachiket wrote:Had he done that, the project would have probably been delayed and the media would be badmouthing his project management skills right now.hnair wrote:

I don't know wrt to the Metro systems being discussed. In Dilli, though the tracks may be conventional BG, the carriages are the same SG coaches imported from Korea sitting on BG rakes. So the "advantage" of BG having a higher loading gauge and bigger coach is not being used in Dilli AFAIK. So that "advantage" is really moot.Standard Gauge is about 10% cheaper than Broad Gauge to build , but broad gauge can hold about 15% more passengers. (3.2m vs 3.66m width)
Hitachi locos were used only in the MG section between Madras Egmore and Villupurum (ie the southern lines). Maybe because Japan too has MG largely , the choice. The mainline BG locos were always Oieropean . With gauge conversion, the MG electric locos went the way of the dodo. The Diesel MG locals were made into shunting locos I think by putting them on BG bogies.the panasonic and hitachi traction motors IR uses in WAP locos have proven themselves in the harshest of operating regimes vs sanitized env in japan
“We have installed the anti-collision device on all the trains and the tracks of the North East Frontier Railway and have now received the sanction to extend the implementation to three other zones – Southern Railway, South Central Railway and South Western Railway,” Siddheshwar Telegu, Chief Public Relations Officer, Konkan Railway, told The Hindu on Tuesday.

Bridge itself has speed limit of 30kmph. Driver reportedly halted at Gadadharpur station, just 10km from Sainthia and then speeded in excess of 70kmph.. So signal may not be malfunctioning.
Something drastically gone wrong after train left Gadadharpur. What could that be ???
Why drivers did not apply breaks at all when there was no visibility problem??
Another good question is , why line to that platform was open. Train could have gone to another line as there was already a train on platform. To me it appears that as Vanachal was leaving the platform, the interlock could have been disengaged.
Calcutta, July 20: Railway officials today claimed the two drivers of the Uttar Banga Express may have been drugged by a tea vendor, preventing them from acting to avert a collision with the Vananchal Express at Sainthia station yesterday.
Preliminary investigations have thrown up “evidence” that driver Madhab Chandra Dey and his assistant Nirmal Kumar Mandal had drunk tea during their previous, two-minute stopover at Gadadharpur station, 7.5km from Sainthia, senior officials said.
Whether the tea was spiked, though, appears to be conjecture at this point. Only a viscera report, which will take seven to 15 days to arrive, can establish drugging.
The drug theory was lent some credence, however, by the wife of Somnath Sengupta, the injured Uttar Banga guard.
“My husband had called me (from hospital) at 6.40pm yesterday. He said that when the train failed to slow down as it approached Sainthia yesterday, he had tried to speak to the drivers over the walkie-talkie. But one of them couldn’t speak at all while the other was groaning,” Sangeeta Sengupta told The Telegraph at her home in Malda.
Several gangs have been befriending and drugging train passengers in eastern India with spiked beverages and robbing them, and it’s possible that Dey and Mandal got their tea from one of these. These gangs operate across states and will be harder to catch than a local station vendor.
Pharmacology specialists said a person’s tea or soft drink could indeed be spiked with small amounts of certain drugs such as nitrazepam, which would not change the taste but put him to sleep in minutes, especially if his stomach was empty.
“Once a train is put on a particular track, the (convergence/divergence) points behind it are set in such a way that if the next train flouts the signal, it will be diverted to another track. It seems the operator didn’t set the panels properly,” an official said.
Railway sources defended the Uttar Banga guard against criticism for not applying the guard’s brakes to stop the train.
“As a rule, we don’t encourage guards to apply full brakes. If the guard applies the brakes from the rear while the driver is running the train at full speed, the train can be snapped from the middle,” an official said. “The guard’s brakes are meant mainly as a signal for the drivers to stop.”
Gadadharpur (Birbhum), July 20: Three white plastic cups and three used tea bags lying on the tracks and platform of this small, sleepy station may hold the key to the mystery of the train crash at Sainthia, 7.5km away.
If the Uttar Banga drivers did drink drug-laced tea during their two-minute halt here, just seven minutes before the 2.02am accident, they would have had to buy it from ghosts. At 1.53am, when the train rolled in for its unscheduled stop, the platform would have been deserted, local vendors said.
But then, it’s only ghosts who could have sold the plastic cups. No vendor at the station or the stalls outside sells tea in plastic cups, station officials and hawkers said. None provides tea bags.
No one knows if the drivers drank from these plastic cups, but the mystery still remains: where did the cups come from?
Or could they have been placed conveniently by an interested party after the accident?
Two of the cups, with tea bags inside, lay in the foliage by the tracks just to the right of where the Uttar Banga’s engine would have stood — a throw away from the locomotive’s right window. Nearby lay an empty, crushed pack of cigarettes.
Did either driver smoke? It wasn’t clear tonight.
To the left of where the engine would have stood, on the stone chips between the tracks and the platform, lay a third cup — just under where the locomotive’s left window would have been. The third tea bag lay on the platform, just above the third cup. Who was the third drinker?
Beside the tracks near the third cup lay a second pack of cigarettes, empty but new, as evident from its shiny plastic cover.
“If the Uttar Banga drivers indeed drank tea here, they must have got it from someone travelling on the train,” said Pintu Das, a hawker who sells lemon tea at the station in earthen cups.
If he’s right, one possibility is that it was one of the gangs that drug and rob passengers.
“Only local trains stop here. The Vananchal had passed the station at 1.43am; the Uttar Banga stopped briefly because the line wasn’t clear,” a railway official said.
It’s impossible to say what happened after that. “No one except the assistant stationmaster spends the night at the station (in his office). The ticket counter closes at 11pm after which no local train passes the station,” an official said.
Even the four shops outside the station — two selling tea and telebhaja and two selling sweets — close by 10pm.
“You will not even find a beggar sleeping on the platform,” said Kishen Sharma, a hawker who sells jhalmuri on trains.
Government Railway Police (GRP) sources said their officials and those of the railways, Railway Protection Force and the state criminal investigation department (CID) had visited the station yesterday afternoon.
“But they did not seize anything from the spot,” a GRP officer said.
Calcutta, July 21: The interlocking system that could have diverted the speeding Uttar Banga Express to an empty platform and prevented it from ramming into the Vananchal Express at Sainthia station on Monday had not been activated, preliminary probe by the railways has revealed.
I suspect that line would have been cleared ( interlocking disengaged) since Vanachal was given green signal to start. Normally route is cleared once departing train reaches the next station( may not be scheduled halting station). However to avoid delay for next train, routes are cleared even before train has crossed the outer signal. This has been implemented on routes which follow auto signalling and keep a gap of about 1.5 to 2 Kms between two running trains.Somnath Sengupta, the guard of the Uttar Banga Express, told reporters after the questioning: “The home signal (signal located 500 metres before the platform) was red. I tried to contact the driver repeatedly over my walkie-talkie but did not get any response. Then I applied the emergency brakes,” Sengupta said.
Mohammad Nayeem, the driver of the Vananchal Express, said that “even though the green signal was given at 1.54am, we could start the train only at 2.01am because we had not received any signal from the guard”.
