I am surprised to see that people are voting for PNBE Rajdhani; are they voting based on any data or just because they love that train? It is very obvious that upto/from MGS, all the pair of Raj make or do the same OTs and HWH/SDAH Raj goes via Grand Chord covering a much longer route OT even more trains. A general rule of thumb on this route will say that longer the route, more the OTs done.
