I just purchased a Lionel 2337 that I place on a track and it will occasionally bind up and growl almost like gears in the drive truck are binding. As a newbie to fixing these engines I was wondering which gears should I look at that would most likely cause this problem. It starts real smooth and runs fine, then for a short distance of a foot or two it will slow down and eminate sounds like binding gears. Do shafts wear on these units or should I loook for worn gear teeth? Thanks for any input. Yes , I have lubricated it before running it.

Mickey,
Exactly what did you lube? Did you disassemble the motor and truck to lube it? Go to http://cgi.ebay.com/LIONEL-POST-WAR-2337-GP7-WABASH-C-7-EX-PLUS-HORN-WORKS-/120644484430?pt=Model_RR_Trains&hash=item1c16f8bd4e#ht_9996wt_905 to see pictures of a disassembled unit.
If the engine has been run a lot without proper lubrication, the armature bearings can become worn and allow the armature to rub on the field. This will give symptoms like you describe.
