What are the differences between the Tyco Chattanooga-style locos, and the later Mantua 2-8-0s/0-8-0s? They both appear to be based on the USRA 0-8-0 switcher. For instance, are the Tyco boilers and cabs plastic, and the Mantuas die-cast?

Here's why I'm asking: I like the looks of the Tyco Chattanoogas, and the fact they smoke. I don't like tender drive, or the look of the tenders below the tank, though. Perhaps it wouldn't be too difficult to fit a standard motor and worm gearset into the engine?
Or, would it be easier to fit the high-capacity Chattanooga smoke unit to a Mantua engine?

I'm not a fan of the drive in the tender either. I pulled mine apart and had to do alot of work on it. I do not beleive it would be possible to put a drive in there, unless you lose the smoker. I'd have to double check mine, but I'm pretty sure you'd lose the cool smoking pump inside in the process of the mods for it. It doesn't run that well on my layout because of the front trucks anyway, my turns are to tight. Anyway good luck with the comparision. I only have the Chattanooga...and probably won't mess with the steamers too much anyway.
Cheers,
pid

Thanks for the reply, pid. Which driver axle actuates the smoke pump?

Here's what I went through motorizing one.

^ Thanks Ray, for both the inspiring photojournal, and the 2 Guyz link. That rebuild was a LOT of work! Great result, too.
Looking at Tony Cook's 1978 and 1992 Mantua catalogs, it appears the Mantua 0-8-0 switcher was driven from the second axle, and that they had plans, at least, for smoke. Maybe, just a Seuthe-type unit, though?

I had and finally sold the Mantua 0-8-0 in the fall. They used a more or less conventional Mantua drive with motor in the firebox. But to convert the 2-8-0 version would be a ton of work and there would be no room for the smoke unit.
Before I went to that trouble I would pick up an IHC 2-8-0 and take it apart and see what retooling was done, if any. The boiler and cab are from the same dies as the Tyco engine. I'm not sure how many other parts are the same. But the drive is a little better and more modern than the Mantua, some versions even have a can motor with flywheel.
If you're lucky it might be possible to just swap over the Tyco cab, boiler and cylinder saddle (where it's painted to match) and then one would only need to adapt a boxcar floor to the tender shell to elimnate the original drive system.

| I have a couple of the later-Mantua steam engines (2-8-2 and 2-8-4) which came equipped with the Seuthe smoke units. The unit that came with the can motor actually needs a lot of speed to really get smoking, probably because the motor draws so little current. The open-frame motors draw more current, so headlights, smoke units, and passenger car lighting seem to work better.

| Thanks for the replies. I'll check out the IHC. As for the can motored Mantua, perhaps you can get better performance with a lower-voltage Seuthe unit.
