They should last more than that. The average service life of a locomotive is around 3.5-4 million miles.

@iRECKONER shops that service loco rewheels usually have a drop pit. A section of rail drops down like an elevator and the new motors are lifted up to the unit on that section of rail - one at a time. Its actually very simple, traction motors basically float and are not held in by much.

@okiebill1948 GE claims their new AC traction motors will last one million miles.

'Lifting off the bearing box', funny they tried lifting it back up..that's gotta be 450-500 pounds... I worked at a machine and Welding shop here in Sacramento, Calif, we had a wheel press for the passenger/cargo axles, and used a lot of the Timken cartridges for wheel and shaft work in rock crushers..I got a real good feel for estimating weights from stuff like the railroad has, but they pretty much doid all their own machine/welding. We did do a lot of hyd cylinder repair forthem though.
