Coimbatore overnight demand is from long time but they have introduced Uday. Not just this sector they are many sectors in India where people travel in buses due to non introduction of dedicated trains and the number of buses ply in the sector is equal to 2 overnight trains yet IR is not interested to increase their share in travellers preferring night travel. I have studied the the routes of all 35 VB routes and found that most sectors need new intercity trains and they are not connected till now and already running intercity need new trains to cater to existing traffic.
