If the auto reverse moduals put out DC and your tortise switch machinews run on 2 wires and DC, from what I would think you could put some type of relay that is timed to let current flow for as long as the switch machines need current, you would only need to run the tortice wires through the relay then to the output on the auto reverser(s). Because then If the current polarity from the Auto reversers change then it should switch the switcher. I'm not sure if it works that way though.
