there is a big mistake going on in railways website, i dont know who is taking care for Arr/Dep history, its just a FAKE
I travel in this train on 11APR and it stated from Santragachi around 1 hour late and even reach Chennai 1 hour late.
Because of this i lost my Bangalore last train, so GUYS dont trust on them. They mansion that train reached in that particular day on time...which is just a BIG FAKE ! Be carefull
