19 Locomotive Types: Diesels, Electrics, And Turbines
Diesel engine or gas turbine is connected to a generator:
orspower from overhead lines passes through internal
step-downstransformer. Electric power is regulated and
transmitted tosaxle motors in the trucks, hence diesel-electric,
(AC or DC).
A=one powered axle 1=one unpowered axle
B=two powered axles 2=two unpowered axles
C=three powered axles 3=three unpowered axles
D=four powered axles 4=four unpowered axles

Ao, Co,... is sometimes used for an axle with an
independent traction motor
