Dear sir,
I am ramanand sagar, had to travel from barddhaman junction to guwahati on train 07149 secunderabad guwahati special (Pnr number: [protected]). But train was late, it's scheduled departure time was 12:52 and the estimated arrival/departure time was 17:59/18:00. I reached the station (Barddhaman junction) by 17:30 but train had already departed from the station before 17:25. The train running status and booked ticket proofs are attached herewith.

Please, reply and try to resolve the problem.

Thanking to you...
