Nostalgia & History > Milwaukee Road F40C at Chicago Union St -- Dec 76

Two year old F40C #40 (Village of Bartlett) is at the north side of Chicago Union Station.
It was retired in 2005.

Nice photo!

Thanks for sharing.

What was the purpose of the two plates above the exhaust stack?

I'm was wondering about that too!  I enlarged the area in question.

Are they hinged stack covers that open depending on the volume of exhaust?

They look like signals and a signal case on the track behind the locomotive.

I tend to agree, as there is only one exhaust "stack" from the turbocharger on an F40C.

The early RTA F40's had the same stack, as can be seen here:

As I was once told:
"those funky baffles that rotated the exhaust flow were designed around C&NW's Bush train shed, which had long slots for exhaust dating back to the steam era."
The E's had narrow exhaust stacks, the F40 series, didn't.
