As the title says really. I keep seeing these numbers cropping up when looking at locomotives etc but have no idea what they mean.

Anyone :-)

It's the configuration of the wheel layout, most popular are the Whyte Notation and the UIC classification.

The basic difference between the two is that Whyte counts wheels and UIC counts axles.

Britich steam is usually classified by the Whyte method and diesel/electric by the UIC method

Wheel arangement / grouping. first instance, 0= no leadbogie ,6= 3 axel coupled drivers, 0= no trailing wheel group. 2nd example, 1 axel leading -2 axels coupled drivers,-1 axel trailing. This is for steam locomotives. diesels have alphanumeric notations and refers to axel arangments . 2-4-2 would be 1-B-1, 0-6-0 would be a' C '. I hope this helps. K.S. 4-6-6-4.( an articulated logger).
