After so many days 12398 came on time at gaya jn.12397 is one of the fastest non rajdhani train and 12398 has an average speed of 61 km/hr bcoz it has to get overtaken by five rajdhani's and one garib rath. Now a days ncr deliberately delays mahabodhi exp so that bsk reaches kanpur before time.it is the fault of indian railways which has given this timetable to mahabodhi exp as it takes only 5 hours from ndls to cnb which is impossible for a train with an mps of 110 km/hr.
