There's another one, wearing a newer L&N paint scheme, in the background on the adjacent track. Several of these "lightweight" GP7 locos - also note the small fuel tank - were originally built in 1950 for the NC&StL, and became L&N locos with the 1957 merger of the two roads.
From April 1996, ratty-looking CSX GP-30 Slug 2263 is on the point of a grain train at Shenandoah Jct., WV. The 2263 was rebuilt from an ICG/GM&O unit. Thankfully, CSX's "Stealth" scheme had a short life.
Thinking of GM&O GP-30s, I found a very tired ICG 2251 at Paducah, KY on 04/11/1987. She's former GM&O 501 and rides on Alco trucks, sourced from GM&O FA-1 trade ins.
Thinking of the GM&O, I found GP-35 611 the same day at Paducah, also riding on Alco trucks. It later became ICG 2510. Sister GP-35 ICG 2515 sits behind.
From 03/20/1997, the 2764 at Darling, AZ and on 11/12/2002, the 2445 at Surprise, AZ. The 2445 serves on the RBM&N today.
Nice view of the inductive trainphone antennas. The GP30 was the last class of PRR locos to be delivered with them.
I believe the New Haven was the only electric line in the US to use triangular hangars for the messenger and contactor wire. This design has since been removed, whether by Penn Central or Amtrak, I don't know. Wikipedia has an essay of the New Haven's early experimentation and installation.
The NHRR triangular style catenary was removed, and replaced with a constant-tension design, 20-30 years ago in NY state by Metro-North (Commuter) RR and in CT by their DOT, the respective owners of the line in each state.
Is that semaphore signal still in use there? Alternatively, do any routes currently exist in US that still use this signalling tech?
