Today I found another interresting solution for controlling the locomotives! That board from “Blue Rail Trains” sounds very interresting. It is board constructed for HO scale, but is also able to get build into G-scale locos. It’s controlled by smartphone using the BlueTooth connection. The app is available for free for Android and iOS. This solution is streight forward.
Sounds like THE future solution. Its cheap and flexible!
I already contacted Dave Rees from Blue Rail Trains. They annouced a board with higher amperage to be released within the next 6 month. Very nice contact with Dave. He promized me to inform me as soon as the new board is available.
