can you hear what I hear?

I don't hear anything. Since you lubed everything and it appears to be running great let it go for awhile. There's not much you can do to hurt a pulmor motor.

If you're taking about that slightly higher pitch sound, that's probably dry bearings in the motor, you have to oil the lower and upper bearings.

The high pitch sound may be coming from the motors, did you remove the shell and oil any parts of these mechanisms?

That's because it went past you faster than the speed of sound!

It was the upper and lower bearings. A few drops of lubrication and all is quiet as Pullmor motors can be. Thanks a ton. I thought I made another stupid purchase. I etan it for about an hour and it was great. You guys rock the rails.

Whenever I acquire a postwar locomotive I assume it's been neglected to some point. I pop off the cab clean, oiling and lubricating the appropriate parts, then proceed and do the same to the trucks. In most cases this all they really need to make them run like new. Ahh, the beauty of postwar!

Motor bearings.  Make sure they're all oiled.  You may need to dismantle the motor to get at the lower bearing...

Easy diagnosis, if it's at all high pitched, it's something rotating fairly fast, usually the armature.

Thanks again all, I didn't have much trouble getting to the lower bearings. These are the PW reissues and the motors seem tiny compared to the orinals but I may be remembering wrong. The only disappointing thing I saw was that the gears in the trucks are plastic. They run like a mad dog after the mail man right now though.

One steamer on the CL&W has a mysterious squeaking when running, faint but there.  Lubed everything except the engineer's mustache inside and out, and it's never gone away.  Doesn't seem to effect the running.  Has hundreds of hours on the "squeek".
