hello, I have a question: how do you turn on the passenger lights in the LIRR M7? I couldn't find a button or anything in the cab.
From watching a stream I think I remember that the lights could be switched on via the control panel near the doors in the carriages. I could be remembering the wrong train though, but it's worth a look.
The M7's passenger lights are controlled through the left-hand operating touchscreen, its an option labeled "INTERIOR LIGHTING SELECTION". For some strange reason however, this and the HVAC systems are able to be toggled on and off only while playing the PC version of TSW. These options don't exist on the PS4 version. Therefore if you want the passenger lights on, you have to wait until the train enters a passenger service run, or take over a train that's already in the middle of one. The lights automatically come on in that little setup process the train does when it starts a service.
