That's the problem around all zones of the indian railways. Even RCF has totally taken over AC coachs production from this fiscal year, not a single Sleeper coach will be dispatched from them from now on. Their whole plan is to gradually replace all Sleeper coaches to 3 AC economy class coaches. Buckle up for all full AC trains in the near future.
They r basically revamping the whole railways infrastructure to get toe to toe with european railways, but forgetting that there's a huge difference between indian and European passengers.
Effect...
more... of "world class railways" hangover.
