[DMCForum] Re: [DML] 50 Worst Cars-What Moron Wrote This? (Electric Motors)



In railroad locomotives electric motors (big traction motors that wrap
around the axles) do not last forever. They last a long time, barring
a short or other catastophe, but definitely not forever.

Interestingly enough, in diesel electric locomotives the prime mover
generally outlasts the traction motors. Cylinder assemblies wear out
and need to be replaced, but unless the crankshaft breaks the block
itself goes on and on and on....

The company I now work for has many 1940's era locomotives in lease
service. None of them are still running their original traction
motors, but those with original prime movers have had nothing but
cylinder assemblies (and accessories such as fuel and water pumps)
replaced.
