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 happened if two classes had a 2-8-2 wheel
arrangement I'm not sure. It didn't happen so wasn't a problem?
There is a suggestion that if two classes had the same wheel arrangement then an additional number (the first number of the road number) was used. e.g. There is reference to a 231.3 class. But letters were also used e.g. 141 class is also known as the ZL class!. 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. There is also reference to a CY class. Could the first letter refer to the wheel arrangement? e.g. B means B-B and C means 0-6-0? |
