Sorry, but I don't know much about how the LEDs are triggered. I plan on going that route because it's once and done with no danger of damaging a board. No matter what subway you run, they'll all be sparking. Then you just shut the LEDs off when your running regular trains.
I really like this idea as the sparks that would occur were usually at certain points like a switch. And as each cars truck passes over the switch the 3rd rail shoe would arc. I’ve seen this in person and in videos and will try to find one on YouTube and post it here.
The other great idea is to use a warm & a cool led. That would look great!!!
