I'm bored. Post here some random, obscure fact that I might find interesting

34. Every train on the Gilmore and Pittsburgh Railroad, which operated in Montana and Idaho,

was running in reverse as it crossed the Continental Divide.

Gilmore and Pittsburgh Railroad

Bannock Pass, on the Idaho-Montana border and the Continental Divide, was by far the most substantial obstacle encountered by the G&P. The pass itself is at an elevation of 7,681 feet (2,341 m), some 1,800 feet (550 m) higher than the center of Horse Prairie. Temporary trackage was built over the top of the pass during the G&P's construction, but a tunnel beneath the pass was clearly needed for the railway's permanent use. Since a tunnel to completely bypass the heavy grades of the pass was prohibitively expensive, the railroad compromised by boring a shorter, 600-foot (180 m) tunnel at the 7,575-foot (2,309 m) elevation. To bring the tracks to the elevation of the tunnel, the railroad line included a switchback on each side of the summit; trains ascending the pass would pull into the first switchback, run backwards through the summit tunnel, and then reverse direction again at the switchback on the opposite side.
