Instead, IR should concentrate on running all the trains on time. IR should seriously work on reducing the delay of trains. After achieving this, IR can then plan to increase the avg speed of the trains.
Simply increasing average speed in TT of train will not at all work. Trains with less priority will suffer more than today if its average speed is increased. The train which runs with average 2 hrs delay today will run with average 3 hrs delay after increasing the speed.
