Sh. Murli ji !
Hope, you slept properly later.
You are correct. In Garib Raths, though the coaches are with 3 side berths, still the class is 3AC only. Two distinctions are there - 1. The coach numbers are prefixed with 'G' instead of regular 'B' and 2. The fare list is altogether different as of Rajdhanis or Shatabdis.
Class 3E is there in...
more... Durontos only having been introduced with these trains.
Sh. Raj, please suggest corrections, if any!
Thanks to you, both!
