No sorry, not exactly right now. But for $26 the assembly might be the fastest, easiest way to go. You already know where to find it and a motor & belt will probably cost at least $15 total. I was kind of surprised at the low Lionel price.
NA-not available? Finding and matching can motors isn't usually too hard. A good RC/hobby shop should have a good choice, electronic repair & supply shops can often find drive belts by description. If you settle on an old fashioned rubber band, check it every now and then for cracks or slime indicating breakdown/melting from contact with incompatible plastic.
