I wouldn't lay all the blame on maintenance. Yes some of the bridges are old but with the new track maintenance equipment and rail/sleepers the standards increase every year. And yes the lowly khalasi still does most of the maintenance with very rudimentary tools.Christopher Sidor wrote:Yes there was a report, in 2009 or before that, which said that our trains cannot sustain speeds in excess of 100 kmph for long stretches. They have to speed up, slow down, speed up, stop at stations and so on. This is due to speed restrictions in place. These speed restrictions are due to antiquated bridges and worn out tracks. Again our lack of maintenance plays out. That is why the average speed of our trains in so low at 60-70 kmph for super fast expresses.
What all reports have said is that you can not run a high speed mixed mode rail system, esp. with bulk freight. This is true even in the US where the Acela struggles to get to 150 mph on tracks that are meant for freight. The weight and power needed for Freight damages/degrades rails and other infrastructure, as simple as that. One reason why our ride quality is so low. Note that even in China the average freight speed remains at ~ 35-40 kmph. All the new high speed lines are dedicated passenger lines.
The single best thing to speed up trains would be to create the Dedicated Freight Corridors. This should move 80% of our freight out of the passenger lines allowing them to be upgraded and speeded up. Unfortunately no one appears to be paying much interest on the progress of this project. Much easier to complain about corruption and babu's.


And the cost of High speed lines is much much more. Even in China with heavy subsidies the Wuhan line of 900 km charges about $80 per ticket. Even this does not cover maintenance and running costs, let alone capital interest and depreciation. Prices in Europe are similar and it works because airline are expensive. Also cities are much closer.
