What is the future of these YDMs? I hope they are preserved or moved to other MG territories and not scrapped.

Thanks for sharing. I did several journeys in the FC coach of this train between Bareilly and Mathura Jn in the period 1970-1974 with my parents.

This locomotive is from Abu Road shed which is written on the bottom line of the front plate as ABUROAD. This shed opened in 1966 and soon grew to be the largest metre gauge diesel shed of Western Railway which held 112 locomotives at its peak (both YDM4 and YDM4A). Check out this picture as well.
Bhagat Ki Kothi was set up in 1972 but it was a Northern Railway shed at the time and normally its locomotives would not be seen hauling Western Railway train such as this one.

Traymbak, I do not recollect about BGKT. Later on the M4s were there. But in 1974, I do not really remember.

Did Jodhpur/BGKT hold YDM4s then?

ABR. All these YDM4A of the erstwhile WR were based at ABR. I guess these were manufactured in Canada. The YDM4s at the CLW.

Diesel Loco Shed Sabarmati did not open until 1978 and even then it was holding only YDM3 class locomotives till about 1989 when the first batch of YDM4 locomotives arrived there.

Abishek, 6339 was an NKE engine that, according to official documents, was scheduled for "conversion to WDS-6" in May 2012, so fits with its current shell condition.

Sabarmati?
