"Southern Pacific's Streamlined Articulateds, The Iconic AC-9 Class" features a photographic anthology of Southern Pacific’s unique 2-8-8-4 locomotives. Unlike SP’s famous cab forwards, the AC-9 class were designed for operation as coal-burning engines on the Rio Grande Division.

Even though there were only 12 AC-9 locomotives produced by the Lima Locomotive Works for SP, these are some of the most popular articulated steam locomotives ever produced. We can see why as we watch SP #3811 pass through Silvis, ILL on …

The AC-9 was one of two Southern Pacific Railroad's articulated steam locomotive class that ran smokebox forward after 1920. Twelve AC-9 class locomotives were built by Lima in 1939 and were Southern Pacific's largest and heaviest steam engines, partly a consequence of low quality coal these engines were designed to burn.

Finishing up the Sunset SOUTHERN PACIFIC AC-9. I had to put a universal in the drive that I found at a RC hobby shop. After modifications it works great. The usual, Scalecoat black and Testors clear for the finishes. I also mounted the speaker in the boiler along with the Tsunami TSU-2200 Digital Sound Decoder to minimise wires from the tender.

Southern Pacific AC-9 Author: SPED After years and years of looking I finally acquired an oil version AC-9, fortunately I purchased a coal version in 2004 but I always wanted the oil version with that 252-R-1 that was the largest tender that the Southern Pacific ever owned.

In April 1953 Southern Pacific was starting to shuttle their fleet of 2-8-8-4 AC-9 articulated from the Southwest where they had begun their operations to the Modoc Line. In order to make such movement of power efficient, SP put the big engines on the head ends of freight trains that were already designated to head in the direction of the new ...

An engine I've begun to take more of an interest in: the Dual Purpose SP "Articulated Consolidation" 4-8-8-2 Cab Forwards. Used over Donner, and various steep grades singly, in pairs, with diesels, you name it, lugging heavy freight, OR, …

Page 22 of the Pacific Railroad Society's 25th anniversary booklet has a 1948 photo showing three UP Challengers in the SP Colton yard. On the Salt Lake Division east of Sparks, the chief freight steam power in the '40s and '50s on the main line were 2-10-2s and 4-8-2s, so it would have been common for these types to be used on reefer trains.

As the flyer indicates, power out of Sparks to Wendel was to have been AC-9 3804, but the engine developed mechanical problems at some point and AC-10 4229 and AC-11 4247 were substituted instead. The 3804 wasn't done-for, however, and would remain on the rolls for nearly another year, becoming one of the last two AC-9's to be stricken from the ...
