The concept of unreserved class should have been totally eliminated in all M/E trains by now. They should have continued conversion of GS into 2S done during covid.
250 to 300 people travelling like animals with UR tickets in a GS coach vs 100 people travelling in same coach like humans which is better ? That's the question people should have been asking but unfortunately it's easy to blame everything on rake standardization as if trains with less AC coaches don't run overcrowded.
