What I'm specifically after is the part number for a grooved drive wheel, non-geared wheel. This engine has only one traction tire, and it can barely pull itself out of bed in the morning, let alone a consist of 5 cars. Train Tender has a geared, grooved MPC era wheel, but I would like to stick closer to an original look, and of course, I'm not at all certain it would fit.
Need a part number for the grooved wheel that is on there - one more should do the trick.
