Actually I made RSA to this route only bcoz it was standing for 2 days at Pune. And Pune to hyderabad is always packed in every train so i thought on this route and major point is it must return to pune in time as it has RSA from Pune. So i just needed nearby short trip which will be helpful. Your ideaa is good but m reasons are different. It will take nearly 5 hrs extra so it is affecting another RSA trip departure from pune.
