A helper set has finished a push and waits to return to Binghamton. As I recall these were the very first U-23Bs. Note the short "wings", indicative of the very early production units.
Okay, so it's not the great gray lightning stripe but for a simple scheme it's not bad. Hello, NS, hello NS, come in NS. Earth to NS. Ex-Lehigh Valley unit.
The horizon is level but the track is not. Looks like a struggle upgrade but it's really a helper drifting back down, sorry. Note the stencil on the rusty bridge.
