Southern Pacific Railroad’s AC-7 class of cab forward steam locomotives was the fourth class of the 4-8-8-2 locomotives purchased by Southern Pacific (SP). The locomotives were built by Baldwin Locomotive Works and shared many of the same characteristics of previous AC class locomotives.The AC-7s were only slightly larger than their AC-6 predecessors but they included larger tenders and a beveled cab front in contrast to the earlier classes’ flat cab front.
