The 72 Fast Passenger was the one I took in 1970 on a school trip to Varanasi, Nepal, Patna and Gaya. This train took us from Varanasi to Muzaffarpur, from where our chartered coach was attached to another Passenger to Sagauli, and then finally to a third one to Raxaul. On the return journey, we were attached to a Raxaul - Sagauli Passenger, and then another Passenger which went upto Pahlezaghat. From here we crossed the Ganga on a steamer to Mahendru Ghat (Patna).

have travelled MG Vaishali from Siliguri to Lucknow Jn in summer of 1979. Took 2 nights and one day to cover the distance. The onward journey was Avadh Tirhout Mail (AT Mail) listed here. Thanks Mani, it is a memorable TT for me.
