Silicon Valley Lines: Layout Tour - Quinn

The Quinn Branch bypasses some of the most treacherous, yet scenic parts of the Silicon Valley Lines. Blasted through the native gypsum and styrofoam, this cut-off allows the railroad to bypass most of the Silicon Mountains. Originally intended as a spur to service distant industry, Quinn sees more traffic now than originally planned. The railroad is still working on constructing the mainline through Ravine, Silicon, and Tracy, so all revenue freight headed in or out of Windsor must do so via this branch.
