Deciphering Axles for you?
The three figures (as in 0-2-0 above) denotes axle sequence on steam locos. E.g. 1-3-2 means 1 leading but non-powered axle in front followed by 3 powered axles and again followed by 2 non-powered guiding axles at the rear.
As can be seen from the pictures loco No. 1 had two powered wheels and no leading or trailing non-powered axles, thus 0-2-0.
