I have posted pics of tkd wap7 dead with ldh wag7 in 12823 blog. The loco got failed before kmz. Trains was two hours late at nzm. Also previous time, i talk to lp while reversal at ngp. He also told me that these locos are not that well maintained. Yeh engine toh bina maintenance ke paani ka dushman ho gaya hai. Thats what he told.
