When I was in G scale my favorite loco was a RDC car. I installed a Phoenix sound system and set it up to run on a point to point track. Using diodes at two different points when arriving or leaving the end stations, a reversing unit and settings in the Phoenix sound software I could do the following:
The RDC car would slow down at two different points while entering the station. At the second point it would also start ringing the bell. The bell stopped when the car stopped at the end station.
When it started in reverse direction, it would start slowly, give two toots on the horn and start the bell ringing. At the first point it would increase speed and stop the bell. At the second point it would increase speed again and give another blast on the horn.
I'd like to buy an O gauge RDC car and emulate the above set up. I know Dallee has what is needed for point to point movement with momentum. Is there a way to also automate the horn and bell?
