Dovetails should create a feature where passenger cars lights can blackout when the train is moving and then flicker back on. This can add some realism to passenger trains for all of the routes.
Just ride on an AI controlled 101 in the day, they dont turn the interior lights on so its always blacked out :P
When there’s a gap on the third rail then yes the lights turns off then on but only on old stock the new one got batteries so with existing routes and modern EMUs ( M7 and 377 ) I don’t think it’ll be possible right know
