Bachmann's Tornado model is simply superb to start with, so it provides a truly excellent base to work on. Like many of
Bachmann's models, the Tornado is based around a solid metal frame, with many metal components, and so it is generally stronger
and more robust than some of the plasticy models. Of course, the fact that so much metal is present means that we have to be
doubley carefuly to avoid short-circuits against the frame when installing electrical components, such as loco lamps.
This model used a CT SL51-4 sound decoder with CT SugarCube, but we'd suggest a Zimo MX645R and SugarCube9 speaker now instead.
The smoke generator is a Seuthe #27, which can be made to fit with a bit of effort (some milling, and a new metal chimney).
