I currently have ESM wheels on the following rolling stock:
Jacksonville Terminal Co. 53' NSC single well car, 9-post (9202)
Jacksonville Terminal Co. 53' NSC single well car, 17-post (9202)
Athearn 50' FMC Box Car (9202)
Walthers 70' Cryogenic reefer (9202) ** Note: Model comes with incorrect Bettendorf-style trucks, but ESM wheels fit and spin freely, though a little loose - If car is pressed down onto track, axles can pop out of sideframes. I initially put on FVM .553" and they do not spin.
