Help with headlights

[KCJones]

Wow!! I got quite a debate going

So, Have I got this right? For the RS3 special I am doing for the HSC (See pictures in my forum below) They should carry red tail lights set up in the marker light housing.

That's it, Dick, and they should only show red to the rear if there's nothing coupled behind them. BTW, I've seen those screenshot and I'm amazed. I spent a lot of time riding the Pennsy in the '50s and '60s, and I remember these units well.

Rules state that a dimmed headlight can be used in place of marker lights. But there is a catch 22 to it, if a locomotive has marker lights, they have to work. Even if they are plated over. So it's cheaper to remove them completely. Passenger locomotives must still have them (I think). Almost all of the Class I's have removed them. Only CSX (with it's ex. Conrail stuff) and Canadian National (on units set up for DPU) still use red markers. ...

Thanks kindly for this information, Chessie. This has been really helpful. While I was generally aware that current practices had changed, I had no clear idea of what these changes were in any detail, because it's been a couple of decades since I've been involved in actual operations.
