Technical we could have run 10 trains, but it only has 5 throttles, so you
have to switch back and forth. If you need more power, you can add as many
boosters to the layout as needed. MRC sells a DCC booster rated at EIGHT
amps.

With the MRC Command 2000, you must do as Chris explains, but with more
expensive systems, you can use the "MU" or Multiple Unit function to link
any number of motors of any number of addresses to be controlled by one
throttle.

Again, the Command 2000 requires all trains to be stopped, more expensive
systems do not. A motor can be reprogrammed in seconds.

Chris is absolutely correct. I choose to hook up the headlight function to
the power plate. You could hook up an "accessory" control instead.
