SER and ECR have suggested taking a train from PNBE to RNC (in the case of ECR) and from HTE to PNBE (in the case of SER). But nobody knows what will happen.

Dono SER aur ECR ne VB ki suvidha di hai
PNBE - RNC ke liye ECR mein
HTE - PNBE ke liye SER mein
Kuchh pata nahi what will happen.

Yo, just wanna add somethin' to your already well thought-out post. Check it - Kolkata, as a big city and all, has lost way more trains goin' to Delhi than any other metro out there. And that's while the population keeps on boomin'! Instead of addin' more trains to Delhi, they just cut back, know what I'm sayin'? I think it's all part of a plan to force people onto airplanes, and it's kinda workin' but what about the small towns and poor folks who gotta travel in crappy coaches 'cause they can't afford no AC? Standardizin' the trains has been a straight-up nightmare for a lot of people. But luckily, Eastern Railways ain't been hit as hard by this mess, and most of the popular trains still got a decent number of sleeper cars.
