Recommendation needed.

I need to install an 0-scale operating crossing gate, with slo-mo operation and bell sound. Any recommendation for the best-looking, and good price?

I want one that doesn't have a big unsightly bump where the gate attaches to the mast. In other words, one that might be operated via an under-table Tortoise motor.

Also, if it's not asking too much, I would like it to have the lamps, operation, and sounds wired independently, so that the operation is prototypical.

Bell, followed by lamps, followed by gate lowering, then bell off.

Gate raising, then lights off when the gate returns to upright position.

Thanks, folks.
