You should book your ticket for Monday departures. This train usually reach Delhi with 5hrs delay on Tuesday. Railway is wasting a huge amount of money for this train. Dynamic fair caused lack of bookings. This train has power generators continuously burning fuel. If you are willing to travel with same budget, I would suggest you to book your flight or opt for Rajdhani express(taking half time). You will not regret. One more thing, this train doesn't have curtains(Like 2nd AC) that we have in other Humsafar express.
