this is mainly to clear pongal rush for people traveling to Krihsna and Gnt dist from Hyderabad
Gnt-Tpty can be tried with a Jansadharan with rake of tpty-pdy which is idle for 5 days week and will be more helpful than DD in Gnt-CtO
There are significant trains as spls like Tpty-SC-CCT-SC-Tpty and SC-CCT-Tpty-CCT-SC but they are no so flexible for dist of Gnt/Krishna as most of bookng will be end to end
