I can’t tell if the number boards are lowered for some reason or if the entire cab has been raised a few inches. If anyone knows about these locos could the please shed some light on this subject.
You can tell it is a Geep rebuild by the radiator and other features, a true GP15 is basically a miniature Tunnel motor. That being said, one of my fondest memories is a GP15 pulling a disabled Conrail (now NJTransit) passenger train along its run. Considering the U34CH behind it was twice its size, a very interesting scene.
