I with my wife and daughter boarded train no.2445- Uttar Sampark Kranti Express on 21.04.2007 at 11.30PM for Jammu. My seats were reserved in Coach No.S5 with birth no. 41 to 43. I was stunned to find that some people had already occupying my seats and inspite of my showing them the duly reserved ticket, they declined to vacate my seats and instead started using abusive language. They claimed that they have been alotted these seats by TTE Sh.Manjit Singh. When I traced the TTE Sh.Manjit Singh, he was under the influence of liquor and was sitting in AC compartment of the train. On that very day, no TTE of railways ever came to our compartment S5 to check the tickets upto Jammu. The compartment had more than 40 passengers who were not having reservation in that very compartment. But so called TTE Sh.Manjit Singh who was responsible for this situation was enjoying in AC coach . I am of the opinion that all these unauthorised people had paid extra money to TTE Sh.Manjit Singh for being accomodated in coach S5. When I approached GRP staff on duty in the train, they also did not cooperate. I and my family could not get our reserved seats upto Ludhiana.
