Don,
This is all I could find. Do you know of any more information on the web?
This may be a photo of it on Sakhalin Island. It looks similar to an S160: [parovoz.com]
from this page: [www.parovoz.com]
There are 8 pages of Sakhalin Island railroad photos-just change the page numbers in the URL.
The link to the English language pages no longer works since the site moved.
Also the message below mentions it.
Thanks,
Bruce Pryor
