Second the bell will put out a lot of voltage spikes. If you are running modern equipment with PC boards,it is best to power the bell on a circuit separate form accessories with PC boards,LEDs etc or at least add a TVS in the circuit,preferably across the leads of the #69 bell.

All true. However, the issue at hand is getting the insulated track to work properly.
I would also put a on/off switch in the common because this bell can be annoying.A push button to ring the bell is also nice.
