Co-Co Diesel Electric

These three locomotives were used on the standard gauge (1435mm). They were imported from China and were numbered 2006 -2008. The locomotives are classified as DF1/DF3 in China and were built in 1972 by the Dalian Locomotive Co. The main photo above depicts D16E - 2008 outside the Yen Vien Locomotive Workshop They were amongst the earliest Chinese diesels and were based on an even earlier Russian model. They were apparently used for Yen Vien - Dong Dang freights and were rated at 1800 hp but were down rated to 1600 hp in VN service. It would appear that at least one locomotive has survived (at least up to 2004) and is stored at the back of a shed in Yen Vien. There is a suggestion also that the original 3 were somehow cannibalised when parts became scarce.DATA
The second and third photos show one of the Vietnamese DF3's in a workshop at Yen Vien in 2004 (road number not known). The colours seem to be the same as the Chinese locomotives but the Chinese Railway logo has gone replaced with another logo. The photos are stills from a video so a little fuzzy.
There is a suggestion that the locomotives may have been painted blue at some time, some Chinese locomotives certainly were.
The two photos of the VN locomotive were provided by "H2M_Ic" on the Vietnam Railways Forum.
Steam Locomotives generally used the traditional French classification system. A steam locomotive with a 2-8-2 wheel arrangement is classified as 141 class, a locomotive with 4-6-2 wheel arrangement is classified as 231 class etc. Pretty straight forward, except what they did if two classes had a 2-8-2 wheel arrangement I'm not sure. It didn't happen so wasn't a problem?
Diesel locomotives have a completely dfferent clasification system.
All diesel classes start with the letter 'D' (for diesel?) then a number which I believe is related to the locomotives power output. The third character defines Electric' (E) or hydraulic (H).
e.g. D5H class = Diesel + 500 hp + hydraulic.
Again, what happens if two classes are the same I don't know.
I am still investigating pre 1975 classifications. Some are the same e.g. 141 steam class, and some are different e.g. 'BB' class instead of D9E.
