well guess we need to consider the fact that SHC has currently only 2 PFs and to add to the problem for train to move towards Madhepura, loco reversal is needed. so any train which is going towards Madhepura from SHC is going to get delayed and also in all probability going to delay some other train as well . Currently work being carried out to add 3 more PF's at SHC, which should take one more year to complete, but as of now no plans to solve loco reversal problem. so railway only planning half solution for this section.
