Humsafar is nothing but an AC Superfast with 3AC coaches. Just like the fact that every RM wanted trademark trains under his tenure, Mr Prabhu went for the same with new livery and additional facilities (something that should always be started with Rajdhanis, in my view). But so far priority is concerned, I see no reason for a Humsafar to get a Rajdhani priority. The train has been put under 'superfast' category and the base fare is less than that of Rajdhani. In fact the only train having such features are Durontos. SO I donot see any reason of Humsafar getting priority equal to that of Rajdhani. However, it will be nice to see competition of Humsafar with SK, SG, WBSK in coming days. That will make things more clear.
