Here is the ebay page.........
these motors are 6 to 12 volts DC....I think Lionel list there's as 6 volts......I have gone thru a dozen lionels so anything is an improvement .....You will need to test each motor and determine polarity of each (you want it to run counterclockwise) I used a 9 volt battery to do this......good luck
