On 12th at Vskp Chennai Howrah mail actual arrival time is 750 arrived at 2100 while Chennai Howrah Coromondal scheduled at 1950 arrived at 2130. One rake of the 6 RSA rakes is late by 12hrs from the past one month but nothing is being done to break the chain by SER. All night trains are departing HWH late being rescheduled atleast once or twice and in return towards HWH are late by 4-8 hrs due to less turnaround time. In HWH SM or PM takes 10-12hrs which for Chennai mail Coro RSA though mail arrives late by 12hrs and coro rescheduled by 8-9hrs same is the case with Pune HWH Azad hind exp. They should cancel atleast once or press an extra rake to break late chain.
