Four O'Clock Factoid: Donner Summit

Four O'Clock Factoid is a daily feature on Track Twenty-Nine helping to get you through the workday with a bit of useless knowledge.

The Summit Tunnel near the top of the Donner Pass along with the railroad approaches to it constituted the most difficult engineering feat in the construction of the Central Pacific Railroad. Completed in 1868, it was in continuous use until 1993, when Southern Pacific abandoned the route in favor of the newer, lower Tunnel #41.
