D4.5H/Matisa M1000
B-B-B Diesel Hydraulic Recording Vehicle

D4_5H001

D45Hthumb002
This 450 hp (hence D4.5H) model M1000 'locomotive' appears to have been built by the Swiss firm of Matisa in 1997 (see builders plate). In one sense it is not really a locomotive but rather a test vehicle. Matisa defines it as a 'self propelled multi-function recording vehicle'. The machine is designed to:

1. Measure track geometry
2. Measure rail profile
3. Measure rail corrugations
4. Measure rail flaws using ultrasound

The machine has an unusual (for Vietnam) B-B-B wheel arrangement.  Looking at the images above, apart from the colour, there appear to be other minor differences between the unit photographed in Vietnam and the machine as delivered by Matisa (as displayed on the Matisa website). Note the running lights are reversed for example. Underbody details (including bogies) appear different, and the windows along the side are slightly different. I'm just wondering whether there has been more than one delivered. The yellow one looks much 'newer' or more modern. More information when it is available.

Locomotive Classifications

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.
