=>Are these Bachmann motors really better?
Yes. The old ringfield motors have relatively weak magnets, and are power
hogs. Modern motors use 50% or less of the power of those old motors. Also,
manufacturing tolerances have improved - all modern motors and gear-trains
are better than those 20+ year old ones (this is an effect of computer use in
manufacturing.) Result is much smoother running.
=>What is the purpose of the flywheel?
To help the engine continue moving over brief interruptions of power caused
caused by dirty or oxidised track. Works.
=>Do Hornby and Lima also use this motor type?
Lima does. Hornby AFAIK has also moved to the modern motor-gear train
combinations. (Sorry, I avoid Hornby, except for old stuff that touches my
nostalgia nerve. Hornby have been coasting on their half-century old
reputation, though there are signs they have awoken to the fact that the
expected standard has risen considerably.) Lima however has below average
mechanisms - the effect of trying to meet a low price point -- electric
trains are "toys" after all, and many people balk at paying precision
mechanism prices for them. BTW, Lima has declared bankruptcy, and may not be

If you want to know about the mechanism, ask, or insist on return rights if
not satisfied. There's no point buying stuff that disappoints. AFAIK, _only_
Hornby ever used the ringfield motor. It was an attempt to increase motor
efficiency given the weak magnets available at the time. Worked well, but has
been surpassed. BTW, many so-called "can motors" use a ringfield, too.
=>Thanks in advance,
Get your trains up and running, and then replace the locos or upgrade their
mechanisms as time, talent and cash permit. Many of the old locos will no
doubt end up on the display shelf -- I have a soft spot for old Hornby
myself, but don't run any of it anymore. :-)
