ek sawaal teen baar!
this train which is a normal Super-fast runs in a super-dense sector of IR with a mind-boggling number of trains with higher priority (Rajdhanis, Durontos, higher MPS trains and then other VIP trains) running at the same time.
Hence this train is forced to be looped multiple times and overtaken by other trains which results in this train getting delayed a lot almost all the time.
