Reply to "Subway track spark simulation"

What they are simulating is the third rail shoe coming off the third rail under load. It is nicely done. It appears that the flash occurs by a truck and only one per truck. It is well thought out. I do not know how this is being done, but it could be a minor truck mod to provide a contact to ground the LED once per truck. If the trucks had sliding accessory shoes, these could be grounded to produce this effect.
