Interior lights flickering independently at third rail gaps.

So I'm aware that it is possible to have flickering lights at third rail gaps, by combining Beacon 20 with a power indicator pluginstate in the train that is linked to off/On states of the train, but the thing is that the whole consist is affected at the same time, while I want to have each cars to have their lights flicker individually while passing over the same gap. Is this is even possible?

Here's a visual example: https://youtu.be/IvHnsai81Ic?t=497  at 8:17.

There's nothing universal I can think of off the top of my head

If you wanted to tie this effect to a specific train, it'd be possible to hardcode distances into the animated file, but that's a mess.....

I've actually got voltages and stuff in an incomplete WIP here, which needs revisiting:

(There's someone with a plugin using three different voltage systems out there too.....)
