on 28th april myself boarded sadbhavna express for ballia in sleeper coach.that train came on platefarm no.10 after 4pm,whereas train's departure time is 4.20pm,that day it was large crowd came to this train who could not board the train in 20 minutes,my request to delhi railway authorities,kindly park the train on platefarm atleast 30 min.before departure to avoid inconvenience.Coach display systems are also not working on most of the delhi's platefarm which is creating lots of problem to identify the coach.Kindly look into these problems to avoid inconvenience.
