Well it's correct for steam locomotives and shunters (switchers)
(counting the wheels) but there is a newer system for diesel and
electric locomotives:
Powered Axles are given letters A=1, B=2, etc.
Unpowered axles are given numbers for each axle.
For example the power car on the Metroliner would be 2-B or it could be
2-Bo - the 'o' stands for some sort of linking I forget what.
Most common designations are Bo-Bo, Co-Co, then the stranger ones,
1-Co-Co-1 and 1-A-1 1-A-1
