A 4200-series 4-8-8-2 cab-forward steam locomotive is cut in behind a 4-8-4 to double-head Southern Pacific’s Overland Limited upgrade out of Colfax, Calif., in April 1950. The cab-forwards were a special design unique to the Southern Pacific to spare head end crews from the accumulation of exhaust in the railroad’s lengthy and frequent tunnels and snowsheds. That advantage is negated, however, when the cab-forward is not on the point.
