On the English and Japanese wikpedia pages for the D51 there's mention of some that were abandoned in the area of Dalny (I've seen various English spellings of this). With the help of a Russian speaking friend I was able to figure out which word is the name in Russian, and after some copy/paste I was googling it. Here are a few images I found:

one that looks operational: http://trainpix.org/vehicle/70220/#n79098
an English page: http://www.internationalsteam.co.uk/trains/russia02.htm
If anyone is inclined to do more searching, the Russian spelling of the place name is Дальнее
I still want to find it on google maps.
