I travel in this train regularly from SBC-TPTY-SBC. The train is very good from SBC to TPTY. But in return direction, as it comes from Madras, most of the times there is not water in the coaches. I don't know what they do at the yard / shed. I think it is better to run sleeper coaches between SBC and TPTY. i.e. attach sleeper coach when it comes to SBC and remove once it reaches TPTY and vice versa. Any objections ?
