Absolutely correct, even 18030 is running on its worst condition. Anything might happen in in future.
Even one more problem is that, due to lack of pit lines, due to which SER currently wont be able to manage 12703. Only TT is matching for SER.

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.

ER only has to manage its own trains like Poorva, Rajdhani, Duronto, and many trains on patna, malda, njp route. ER always wanted it to be separate.And in HWH old Complex is controlled by ER, I think there is no direct line for south line and trains needed to be diverted via long route. Well you are absolutely correct about maintenance time. Around 20 hrs time is given to most of the trains you have mentioned. And if its rsa is done, can be managed very appropriately. Howrah Puri Express can easily have rsa with any of the trains you have mentioned.

Yes that's true. East Coast had RSA with Howrah Hatia, why not resume that as well? HWH PURI can have RSA with Gitanjali. I said ER because we have some good night time trains that can be RSA partners like Padatik etc that can be suitable for RSA with Amaravati etc. When that happens it will become a full fledged ER train, like SDAH PURI Duronto.

But then, Amravati has to originate from old complex of HWH or from Sealdah. Anyways, 18046 can have rsa with old rsa of gitanjali, 18049 with 18045
And 12860 with 18615. Easily managed. 2 rakes will be saved, and load from SRC will be reduced.

Even 12837 Hwh-puri exp can have rsa with 12860 or 18045.
