I think the 2 tier AC coach of 12905/12906 Hapa Howrah Express should be changed to a new one as they are really horrible. I travelled from Howrah to Vadodara on 18th Nov 2011 and the A1 Coach was not at all good. Air condition was not working fine and even it was shaking very much when the train was on Move.
The Coach attendant was not at all careful when we were telling him for the AC and he was saying it will get cool in just 15-20 mins but it was not the case.
When...
more... we asked the TTE for complain book for noting Complain against Air condition not working he skipped saying wait I am bringing it as the book is kept in another coach.
Mamata Di just have a look on this topic.
