Trains are real heavy, and need a strong surface to support them. If you'd lift a train off the track and put it on the ground it'd sink to its axles. The rails and the sleepers spread the load over a greater area until the ground can support the weight of the train. On top of that the steel wheels roll along real easily on the rails, allowing big loads to be transported using only fairly little power. If you look at a truck you'll see how the tires squish a little under the weight of the truck. All that squishing is taking energy from the engine, all the time. With steel wheels, no squishing and no energy loss. OTOH if the wheels can't squis you need a really smooth surface to run on, or even the tiniest unevenness will shake things apart.

Can bachmann locomotives run on hornby sets?

All model trains are compatible on the same track if they are the same gauge. The only time they may not be compatible is if a dcc chip is programmed not to run on dc.

Can you run 2 oo gauge locos on the same track?

Yes you can but if you do they will both run together on the same power supply. You can get DCC trains which run speratly.


Can Lionel and American flyer trains run on the same track?

No because they use different currents, track sizes, and power methods (2 and 3 rail).

Do you need two controllers for two model trains?

It depends on the type of locomotives you have. Several DCC locomotives can be run on the same track with one DCC controller. Traditional DC or AC locomotives on the same track will only require one controller and they will run at approximately the same speed. (AC and DC cannot be mixed)

Do railway tracks get magnetised when trains run on tracks?

No, however some trains have a magnetized wheel to help grip the track. *Added - Electric trains do result in short term magnetizing of the train tracks. This can be seen on sharp curves where tiny rail slivers cling along in a magnetic pattern. In the US, trains do not have magnetized wheels, but rapid trainsit systems can include a track brake that uses a magnet to provide much faster braking than the wheels alone.


What model trains can run on Lionel 3 track O gauge?

Most models designed to run on 3 rail "O" gauge track will work. Models designed to run on 2 rail will also probably work. On the other hand models designed to run on three rail and having metal wheels and axles will not work on 2 rail track.


Do all model trains run on any brand of track?

Generally if they are of the same scale and the tracks fit each other they will work together.
