BachmannTrains E-Z Command Digital Command Controller

Q: Does this work for tracks that are not "bachmann"? like Atlas?

This item works with all two-rail tracks (HO and N scale), including Atlas.

Q: does it work with HO scale or O scale ???

I used it with HO scale. Although I had both O and G scale trains at the time. I only used it with my HO layout. Jerry

Q: How many HO locomotives can this unit operate at one time? When running multiple engines, can the speed of each be independently controlled?

Hi, i am Carlos and i will answer your question, to activate the locomotive for example on address 2, simply press the address 2 button. At this point, the red LED next to address 2 will be lit, and the locomotive on address 1 will carry on running at it last speed and direction setting, it is called "running in background"Now, to activate locomotive 2, simply turn the controller knob slightly, now this locomotive 2 is activated and you can determine its speed and direction settings independent of locomotive 1, turn the controller knob to set the desired speed, with up to 10 locomotives or addresses at your disposal, you can switch among multiple locomotives in this fashion.in addition, you can program the functions, for instance, locomotive 1 is running forward and you want the locomotive 2 runs backward, one can program the function so that the locomotive 2 operates in reverse, and you can also buy this accessory "Bachmann DC controller" that you can connect or install together with your E-Z Command Control Center.Before i forget to tell you, the 10th function converts from its original DC (analog) assigment to DCC (digital), then the 10th function becomes available, and the connected DC controller will allow you to control DC locomotive in conjunction with your E-Z Command system.NOTE: the 1AMP transformer supplied will run two locomotives at any one time, operation of more than two locomotives PER E-Z COMMAND CONTROLLER can effect their performance and may require additional power input.
