From 11/19/1988 at Danbury, CT, EMD FL-9 2006 with Hancock air whistle. https://fl9.com/locomotive-horns/hancock-4700-air-whistle/
That triangular catenary is neat! It's a little like the BC Rail Tumbler Ridge electrification catenary. I wish I could have seen that in action...
Be still my heart... ain't she purdy!!! Should have taken a little bit off the steam generator and put it through a real steam whistle!
Sorry for the delay in replying, I never got my computer out for email at Springfield. The E44 was actually in Amtrak livery when donated to the Museum.
I think the color is called Dark Green Locomotive Enamel (DGLE)? In essence, a drum of black paint with a pint of green mixed in...
You have a good eye Doug, very interesting. The PRR did own dual service FP-7s, but @Point353's 9690 wasn't one of them.
I need to look at these pictures more closely! Looks like DL-109s. The SOU owned only 3 A Units and 3 B Units.
