Faced with rough mountain grades covered by tunnels and snow sheds, the Southern Pacific’s unique “Cab Forwards” were a breath of fresh air to the engineer and fireman. The ultimate development of the design, the AC-12 4-8-8-2, battled the Sierra’s from 1943 until 1958.
The AC-12 saw service on a variety of trains. They were used on general freight, priority produce trains and occasionally as helpers on heavy passenger trains. Even these huge machines were often seen working in pairs or more with locomotives placed at the head end, mid train and on / or on the rear to get the heaviest trains over the mountains. Despite their success, the AC-12 would have the dubious distinction of being the last new steam locomotives purchased by the Espee.
The coming diesel locomotives were already a “cab forward” design as far as the crew was concerned. Interestingly though, the many tunnels would play a role with the development of later diesels, namely the SD40T-2 and SD45T-2 “Tunnel Motors.”
Only one Cab Forward, No. 4294, is preserved today. It is also the last new steam locomotive purchased by the Southern Pacific. It can be seen strategically placed next to the first locomotive of the Central Pacific, the C.P. Huntington, at the California State Railroad Museum in Sacramento.
