Pic of an unusual shunter inside the Golden Rock workshops by Richard Morrison <r-morrison@ntlworld.com>. He writes to our S. Srinivas (who forwarded the mail to me): Just getting a chance to look at some of the pictures that I have taken, a curious one is one of the works shunters at the workshops. I have attached a copy any light that you can throw on this curious beast.
From my observations I’d say it is not a WDS6, it has 16 cylinders and also has a single driving position similar to an YDM4. My guess is that it is an old WDM2 that has been withdrawn from service and the works have modified it for their own use, if you look closely you can see both BG and MG couplings. Please feel free to pass around anyone who may be able to answer what the origin of this locomotive is.
