Hi,
Someone recently mentioned the fact that 9V tracks can only handle a limited
number of motors/engines (whatever you call them). Also, puting multiple
motors on the track will result in each motor getting less "juice"
(current?). Is it true that using multiple motors in one train will result in
an increase of "power" (be able to pull more), but also a decrease in speed?
Second, is there any point in connecting two speed regulators (with two
transformers) to the same set of tracks?
Also, what is a "buffer"? I assume it's the black piece where you attach the
magnet and the coupling to. Most commonly, it's attached directly to the set
of wheels at a 90 degree angle... Hope I'm correct.
Um, that's all for now. Thanks in advance.
Bryan

| (...) There will be an increase in power, but a decrease in maximum speed. The electrical formulas are complex because the power pack is not an ideal constant voltage source, nor is it an ideal constant current source, thus increasing the load will (...)

| (...) Yes, this is my experience. I find that multiple motors help with traction. Speed, however, hasn't been a concern. (...) No, and if you aren't careful, you can damage them. (...) The buffers, specifically, are the round balls on each side of (...) (25 years ago, 19-Nov-99, to lugnet.trains)

| (...) 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)
