Roadrailer Questions

The other day in class we were talking about train brakes and how they work. I was wondering how many control valves are used on RoadRailer trains. The System Special Instructions don’t say anything about them. Also, do they use the A, …, E, D, C, B units and segments thing or not? Thanks

I think they use a CouplerMate for coulping to other cars and an intermediate truck platform as well. As for the brakes, I have no idea. It should take too much to stop RoadRailers.
