If you're traveling with reservation by Sleeper class on this train beyond TRVL(towards TVC), you are advised to book an Upper Berth or Side Upper Berth(if you have the choice), or climb on to any vacant UB or SU berth, and stay there till your destination, as there is hardly enough space to sit on the Lower/Side Lower Berths beyond TRVL due to the number of unreserved passengers traveling on the section.
