MRC Tech II throttles, well known in the model railroading world, solve this
problem nicely. I have a passenger train with two locos (4 motors) which is no
problem at all for my MRC throttle. I have had some of my train motors for
three years and have not burned any of them out. A cautionary statement, MRC
throttles are 12 volt. This has not been a problem, however. When I first
hooked up the MRC throttle I did some test runs with a multi meter monitoring
the voltage. I couldn't get over 6 volts without running the train off the
tracks. MRC throttles also make it easier to pull slowly away from train
stations and coupling cars.

| (...) This is so,but this won't mean that you can't place 3 or 4 motors on the track. The transformer gives 10V output at a 'power' of 7VA. Some explanation : VA is the multiplication of Volts & Ampere. This means in our case that the transformer (...) (25 years ago, 19-Nov-99, to lugnet.trains)
