I have had my 2-4-2T for about 6 years now. Have kitbashed it into a 2-4-4T and added constant lighting. It will easily pull 5 box cars up a 3% grade on a 8ft curve, providing the track is reasonably clean. Have found that it needs plenty of lubrication and don't go too slow over points with plastic Frogs. If I knew how to, I would post a few pics of it.
