Hasn't 4014 been so equipped? I'm sure I can dig up some in-cab video.

Even back in the '90s, UP locomotives had a transponder positioned above the rails right behind the pilot. It was there to pick up signal indications, even though it could not interact as PTC does.

I hope Hiawatha Pete shows up, as he is well versed in these things.

611 is running in Virginia this month. It's making a trip through Charlottesville.

Thanks, and good afternoon.
