A very good poll.Some infos should be highlighted:
1.Howrah division and Howrah outer is best in punctuality.Here trains only stop ±5 mins. At outer (ER locals).
**Reception of SER locals is poor in HWH (ER manages SER locals' reception officially)...as DN EMUs (as well as Up) gets stopped for ±10 (the reason is unorganised platform reception at SER platforms)
2.Second comes SDAH...as it ...
more... handles many EMUs of Main,North,Dankuni branch & south.But SDAH is very possessive towards its Galloping locals.
3.Third is SRC....though it actually negligible locals terminate here.Shalimar is out of question.
••••Now,an additional info on maintainance of EMU rakes by carsheds (parameters: cleaning & perfect maintainance)
1.BT (barasat)...I am amazed by their maintainance...Though i am very possessive towards my HWH division...but these days...Barasat depot are very hardworking with their rakes...even better than HWH carshed.
2.HWH
3.BDC
4.SPR
5.RHA
6.NKG...very poor maintainance
(Note that none of these carsheds keep MEMU rakes)
