Vijayapura to Tirupati is just a one trip special by SCR. Why can't it be a regular Overnight train by SWR?
If SR runs a MAQ BJP train and RSA train as BJP MAS, it will benefit many people. Say MAQ departure by 1800 BJP arrival by 1230 and RSA BJP dep 1600 to reach MAS/ MS by morning. Return Chennai departure 2000 to reach BJP in the morning and leave BJP by evening to reach MAQ by 0800.
