No.... all the three belong to Ludhiana shed. It seems Ludhiana too is experimenting with new liveries similar to LKO. But whereas LKO has a blue band, the LDH ones have red.

The front of this loco seems to be very similar to that of the WCAM-2,3 & WCAG-1 locos.

I could't find any photos of similar loco in the Hughs NG loco book. But from the notes, this could be the F Class 2-8-2 of Barsi Light Railway(Miraj-Kurdwadi-Latur).

Barath Moro and the storm were standing next to what appears to be a ng loco with cr markings

Hmmmmm....nice one.

This loco can either be itarsi(but no particular designed markings on the front). Most probably it may belong to new katni jn. which is the only shed to hold WAG5s and WAG7s after itarsi.

Is this loco really so dirty or is it an optical illusion?

The stripes are supposed to make the loco more visible from a longer distance away.

They are called "tiger stripes" on this forum. I remember sometime back some of our US-based members remarked that these stripes were similar to some US locos. Could be a coincidence.

Lucknow (LKO), I think.
