I'm a BlueRail fan.
I did an Atlas engine with a BR board and Soundtraxx sound decoder which uses AC track power.
I did 2 MTH F-7s using the PS3 board in DCC mode for sound. They use battery. I have a temp setup with RC batts now but will be doing something more permanent.
If you look at the Soundtraxx TSU-4400, it has all screw terminals. No soldering.
Screw terminals on the BR board too. No soldering.
If you like the use of a controller vs a phone, you can use any MFI game controller paired to your phone. Dave Rees at BR did a video on this.
Feel free to contact me if you want to talk specifics.
Have Fun.
