Hi Tom, this guy is around 15 years old with a ton of miles logged. I changed the battery a few years ago so its good for another 10 years or so. I have a couple of the new MTH RS-3's and they come with smoke. Strange, one has a detailed cab and the newest one doesn't.Nice string of cars. I like the Maine Central box cars. They have a decent weathering effect on them.
The RS3 has great detail, even for an older unit. I always wonder why MTH never did a Premier version of the RS1 or RS3. The Railking units are still excellent and seem to get better, detail wise.
