Just outside the western portal of the Cascade Tunnel the Z-1 Electric crosses the steel bridge over Surprize Creek.

It has 3 powerful units pulling freight West bound on this wintry day.  Built by Baldwin/Westinghouse early in 1928, it ran until it's retirement in 1956.

The Cascade Tunnel is one of America 's greatest early engineering feats being almost 8 miles long and absolutely straight end to end with less than 2% (percent) grade descending East to West.  The tunnel relieved the Great Northern from its history of snow hazards in that area, decreased the distance traveled and transformed the route to a uniform, efficient and pleasant trip.
