Prime reason is punctuality, has gone down the drain. SER's decision to serve all its' division's major Kolkata rush bond points with a single slow premium train is backfiring now.
Except for TATA, this train's route is very ridiculously long and slow for HWH passengers boarding from RNC and PRR. Thanks to CKP division to add extra detentions everyday as icing.
With MSAE's SER-ER connection near the horizon, contributions by RNC and PRR will reduce to nill if VB fails to provide competitive fast and comfortable journey experience.
