Champaran HumSafar Express : इन अजनबी सी राहों में, जो तू मेरा हमसफ़र हो जाये, बीत जाए पल भर में ये वक़्त, और हसीन सफ़र हो जाये. - Piyush Singh

It's pretty easy to catch the train from Tpty-qln to rsa with sc/vskp/ns/ballarshah on Sunday and Monday. The train leaves on Sunday at around 3:20 am and reaches pitline around 4-4:30 am. For example, there's a special train from sun 3-4 pm to sc, vskp, or ns, depending on the destination timings which may vary. On Monday, the train arrives between 4-6 am and returns at 3-4 pm. The departure from tpty is around 4-5/6 am approximately. In the afternoon, it goes back to tpty as qln express. I think it's intentionally left on Sunday-Monday.
