They are long route trains mind you.
You won't be getting a place to even breathe in Sant Kabir Dham Express or Raptisagar.
Chambal has maximum Passengers between HWH-ACOI.
After ACOI the train has lots of vacant seats in the reserved class.
You...
more... can also get a seat in general class.
Chambal runs jam packed till Allahabad, however after that seats in plenty are available till JHS or GWL alike.
Check the availability, you will be confirmed.
