It is a part of a suite of controllers that I use to control my trains. See the collection linked just before the description block in this post for associated controllers. The example train demonstrates most of the collection. When designing this controller, I could not know how you chose to set up your locomotive's actual engine. However, there seems to be two basic categories, A. a locomotive that is controlled by sending a throttle signal to an electric motor, and B. a locomotive controlled by sending a throttle signal to some kind of diesel engine. I have separate drive system modules for each of these cases which connect to the master controller. Each of these has a suite of tuning parameters and features for the specific type of drive system.

how do u tie this into other systems like my engine ecu . what does control and control status connect to ? what does drive system control/feedback connect to ? and how do i tie in the lights to this system without messing up the main light connections ?
