Bo-Bo Diesel Electric
These locomotives were built in Vietnam in 2002 presumably for use on prestige passenger services and were numbered 1001-1002. Only two were built and they seem to have been less than completely successful. As far as is known they are the only locomotives built from scratch in Vietnam. Only one seems to be currently in operation. They seem to have had a lot of trouble with the nose shape. Note the damaged and poorly repaired nose below. I caught a glimpse of one when I was in Saigon in 2009. No idea whether it was operational. The locomotives seem to have been designed to pull coaches painted in the same colour scheme (see images below), but in reality pull anything in the passenger fleet. They look vaguely like the British HST or the Australian XPT power cars, so I wonder if they were designed to 'top and tail' passenger trains the way that the HST and XPT does (see images at bottom of page). I don't think this has ever happened. At least one unit is currently being used on short distance local passenger services around Hanoi often with another class of locomotive at the other end.
Above: These three small images appear to demonstrate the original plan for the class. The third image is probably the original for the 'photoshopped' first photo.
Above: D8E downgraded to hauling a local train and looking a bit sad.
Above: A less than pristine D8E-1002 hauling mixed coaches. Note damaged and poorly repaired nose and also the windows depicted in the 'ideal' photos at the rear to match the coaches never actually existed in real life or have been replaced with grilles.

SIMILAR LOCOMOTIVES IN OTHER COUNTRIES
Above: Top: British High Speed Train (HST) Class 43 in original British Rail colours. Bottom: New South Wales (Australia) CountryLink Xpress Passenger Train (XPT) . Both locomotives are considerably more powerfull than the D8E and can run a lot faster.
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 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.
