somewhat similar like this happened with the locomotive BGKT WDP 4 of The Muzaffarpur-Anand Vihar 12557/Sapt Kranti SF Express a few months ago and Indian Railways tends to increase the speed of Locos.
I don't think that ECR even has a loco repair depot.......even for the maintenance of the locos..... Siliguri is the nearest shed.
Hope for the best for the Barauni (Garhara) Locomotive shed (under construction)
