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?
Railpro runs on 12-18v ac or dc, or dead rail. They have dcc compatibility too. Since they communicate strictly via radio signal they don't care if you have dcs or legacy on the track. Not sure on electric sounds but they seem to be adding sounds quite often. The controllers can be had for 240 street price.
