Runaway Train

All said and done, Indian Railway is battling the ways out in the given situation is commendable.
But.....
The speed is phenomenally LOW. Take the cases of the over-bridges; over the rail or over the road - it takes hell lot of time compared to the other part of the Project. Everything else gets over and then they look at IR to complete there parts!
With this, how IR is expected to keep up the rate of infrastructure development and then talk about high-speed trains?
