Just gone through this post to find a train which terminated 252 Miles before SDAH was searched by you in Station ARR/DEP ex SDAH!!
This post was not a blame on IRFCA but at Indian Railways TT which was & still holds correct!!
North Bengal & East Bengal were different train with later use to cover SDAH-Dhaka-GHY & must show in SDAH Station ARR/DEP but not North Bengal which never show up at SDAH!!
