Added "C" which is technically the classification of Class 08s etc although it seems to be rarely used. Corrected B-B to BB,
The wheel arrangement on large diesel locomotives is described using the UIC classification system. Those in use on the SVR are as follows:
*B-BBB: Four powered axles all mounted in the locomotive's frame, driven in pairs, i.e. each pair of axles is connected by driving rods or gears.
*Bo-Bo: Four axles in two individual bogies, all driven by their own traction motors.
*C: Three powered axles all mounted in the locomotive's frame, all connected by driving rods or gears.
*C-C: Two bogies or wheel assemblies under the unit. Each bogie has three powered axles, mechanically connected by driving rods or gears.
*Co-Co: Two six-wheeled bogies with all axles powered, with a separate motor per axle.
