The entire jhs-ljn section isnt slow....even after being single the govindpuri-jhs route is much better than ljn-govindpuri section which is double electrified line...i travel a lot in this section i.e; ljn-jhs section either by 12521 raptisgar express or gwalior mail..both these train almost run on time upto bbk..but after barabanki suddenly the situation changes drastically..the train gets delayed by almost 1-2 hours..then again after govindpuri the trains make up..
