> when and how Indian Railways will incorporate high speed rail So there are two parallel efforts going on. High speed bullet trains[1]. These require building everything from scratch, tracks, stations and so on. When fully operational, it will be a truly new experience for Indians and hope will boost economy and benefit common man. The second one[2] is upgrading existing tracks and coaches to be run at a higher spee…
I can understand why you might need new tracks for bullet trains (old ones not perfectly level and aligned, quality of materials, friction properties, whatever). But why would you have to build new _stations_ for them?
1. have to switch out the driver position from one end of the train to another end to just leave the station again and
2. have a series of track switches which may malfunction (which ironically is a challenge even for highly industrialised countries like Germany), and it
3. means more and slower track to be maintained.
If you set up a bullet train program, you want speed, and these problems kill the speed advantage. The solution is to build a new station in which the train can just pass through.
