I use a bridge rectifier ahead of the LED lighting (so that when I run at my DC-only club the lights work in both directions). Since a bridge rectifier is actually four diodes, doesn't this solve the reverse voltage problem as well?
Or should I add another diode?

Thanks that makes sense. I will include a diode if I decide to power
LEDs from the track.
