I have a better idea.
Step 1:
Instead of conventional ICF rakes, put up a python rake consisting of BOXN carriages.
Step 2:
Now extend this train to Agartala.
Step...
more... 3:
Bring your bean bags for seating purpose. An umbrella for protection.
Features of this train:
-> Roofless train: For uninterrupted view of sky
-> Airy coaches. No sweating. No need for an AC.
-> Can be good for tourism, railfanning, as well as local people as the train, would take a considerable halt at every other station. Railfans can witness hundreds of O/Xs. And if you see, this would be the cheapest transportation to NCR.
Final Step:
Forward this proposal to RB. IR is very large organization. They might be having a tough time handling it. With this, they might get some things off their minds by having a good laugh.
