What is this?

While photographing trains this week, I saw this new addition to a CSX SD40-2:


It looks like a GPS dome and a warning beacon !?

Antenna and warning light for remote control operation.

 

I thought after the great runaway (SD40-2 # 8888 ) it might be something like remote emergency braking or tracking

So, what's the deal? Are all locos getting this or just SD40's? We had a GP40-2 (#6002) in town last month that had the cab mounted triple set of lights, although they were mounted on the front of the cab, not on top

Harold:

According to what I have read, 100 units will be equipped with remote control equipment. These will be GP40-2's and SD40-2's.

I havent seen any of those down my way, but if I see some I will post pics

I have also seen on another post that this is the indicator light for the stand-by diesel unit that keeps things warm and charged up without running the prime mover. The engine with new paint is an SD50 and has one on the long hood, engineer's side.

Could be, but still need to explain the antenna thingy.

 

Another good explanation
