Went to the Hamburg meet this past Sunday. Bought some nice looking Lionel pw 400 and 404 Budd cars at a decent price. The dealer who sold me the 400 said it runs perfect (yea.... checks in the mail) . First thing I did as usual when I got them home was take them a part to check out the electrical, clean the grease out, re-grease and oil them. The 400 had two wires off the motor and the 404 had one wire off the motor, at the price I paid for both, no biggie. After doing the maintenance they now run like new.
