Future Development

Recently there is Doubling work of Dakuni - Andul (Additional Kolkata Chord link) line is going on to introduce more passenger train. If doubling work completes, a lot of trains would start from Sealdah or Chitpur Kolkata Terminal by which passengers of Kolkata would get convenience. It will alleviate pressure on Howrah. Besides Sealdah will get direct EMU train towards Kharagpur South Eastern mainline section.[3]

gollark: Probably mount configs, I think.

gollark: I mean, I think you can muck around with some option somewhere to not require chmod +x (or 755 or whatever), but you probably shouldn't.

gollark: If someone doesn't know the all the arcane lore of Windows, not their fault.
