myself and my friend ganesh had purchased ticket for ahmedabad at udhna bearing ticket no. k ******** on dt.14/12/10. we got 2 seats in a compartment. at surat a gang of 8-10 passengers boarded in our compartment and they forcibly evacuated our seats saying that the compartment was reserved for pass holders. when we protested they forced us to leave that compartment,we tried to find police but no one was around there.we noticed that there was no sign or writing "pass holders" any where. so, how should one recognize a "pass holders"compartment? who has given permission to these pass holders to misbehave with fellow passengers? they behave as if they have purchased the whole train.many a times i have to travel by train and almost i have this grueling experience of ruffian pass holders.and i am not alone to have this experience but there are thousands of passengers who just don't know whom to turn for help. i think it is high time to take strong action against these ruffians. can not we make different color for" pass holders" compartment? they should be punished for traveling in compartments of general passengers.
