The RailPro boards are all in one. Nothing else to add except the controller. You can also get the USB dongle and control that way. Street price on the RailPro board for O is about 150 and their speed matching system for consists is fantastic, works similar to the real thing.
Well I do not see sounds for Electric Engines, just Diesel and Steam.
It appears it does not run on AC Power... ** RailPro system uses fixed voltage DC power.
While over time the more engines you do the controller cost improves, but geez, nearly $700 for two controllers?
So I assume I can not run my DCS trains on the same track as RailPro controlled trains (unless I make them BPRC?
