I wonder why there is a lack of pit lines in Kolkata. Probably many trains have huge time dedicated to PM here. They should think about transferring some South bound trains to ER maintenance to ease the load from SER. Amaravati has around 22 hours PM in PDPK or SRC. Same with East Coast, Gitanjali, HWH SMVB SF and a few other trains(huge PM time allotted). While SMVB HWH should be reverted to it's previous TT(2 nights 1 day). They should be managed with RSA to reduce standing time in pit lines. Falcon can depart late night from SC and around 2130 arrival at HWH but SCR won't do it because they might have to manage OT of SC VSKP duronto, SER has to allot time for PURI HWH Vande Bharat OT as well.
