The key brilliant insight that Matt came up with in the design was to utilize the original tunnel as a double track line, and then use the newer tunnel as a single track line in order to accommodate the triple NTRAK mainlines on a location that really only had two tracks through the tunnels.. To quote John C Paton from "Alleghany with an A",
"Curiously, to look at them, the impression is that the old bore is really the new one, and vice-versa. This is because the new bore was drilled for single track, while the old one is wide enough for two." The single track in the old bore gives the feeling of spaciousness associated with a newer excavation."
The main scene at Alleghany includes a turntable, brick cabin and depot. |
