I said that my train had undergone Diesel Loco Failure... our train's loco had to be replaced with another spare loco that I think was arranged from Jagadhri Workshop Side... I was skeptical this time also (Dec, 2012) when my Durgiana Exp was crossing Jagadhri - Darazpur Stretch but then there was no failure this time with a fit GZB WAP-7 from SRE to ASR :-D
