Initially prna-dmh was highly low mps section 50 (practically 40 or even lower then that )..May be attributed to new tracks led in highly flood prone areas and initially when the services were started the same was started keeping the mps low ....Now entire section has been increased to 100 mps as far as I know ....dmh-shc was already on 100 since commissioning . But timetables of trains are yet to be changed ...Humsafar is being diverted as per news ...Rest other trains in route may be speeded up ..Let us see.
