So, is there any chance of it working in the other direction - Railmaster or stand alone Elite/Select controlling a loco with one of the new Bluetooth decoders fitted via the dongle & phone/tablet? As I see it, this is just for loco control? It has an awful long way to go to give the functionality of Railmaster. If the two can be used together that is fine. In my case, I have a good desktop computer, a good laptop (running Railmaster) & a good phone (which has the Railmaster mobile app installed). I rarely use the phone because of the small screen. I neither need nor want a tablet. So, it will be interesting to see how this develops. I did notice, however, there is absolutely no mention whatsoever of Railmaster in any of the blurb to date. Make of that what you will...
