Due to lack of coaches SER cannot run many trains like some names are
1. HWH-ADRA
2. KGP-HTE
3. SHM-LTT
4. SHM-BHUJ
5....
more... HWH-JDB running Triweekly
6. TATA-ERS not running daily
etc, etc many other trains.
Reply is correct but RB is not solving this issue and allocation of required coaches are not done by RB even after many letters from SER to RB.
Also coach Allocations are also very slow for proposed lhb trains of SER in 2021-22.
