Mystery Locomotives (2)

It would appear that I was wrong. A correspondent on the VN Railway Blogspot from Taiwan has identified the locomotive with side rods as a Japanese DD11 class 'sent to Vietnam in 1977 as a gift' and that it was numbered DD11-2. Now that I compare the locomotives it seems obvious. The mystery locomotive is clearly bigger than the Whitcomb machine and is longer.

Shows you even I can make mistakes!

Now we need to find out it's history in Vietnam. Interesting that two different locomotives built in different countries at about the same time could look so similar!

It would appear that there were two types numbered 1-3 and 4-9. Types 1-3 were built in 1954, so our Vietnamese loco (no. 2) was built in 1954.

The locomotive was apparently operated at the Kobe Freight Terminal of Japanese National Railways before being sent as a gift to Vietnam.
