Southern Pacific 4294 (4-8-8-2)

SP 4294 is an "Articulated Consolidation" (2-8-8-2) built by Baldwin in 1944 as a cab-forward to spare crews the effects of riding behind the stack through tunnels and long snow sheds covered with snow. Notice that the cylinders are still behind the drivers. The locomotive is a simple articulated, meaning that all four cylinders are high-pressure. Some articulateds built by Baldwin for Southern Pacific before 1930 were compound locomotives with two high-pressure and two low-pressure cylinders. These compound locomotives were later converted to simple articulated engines. SP 4294 weighs 657,900 lbs. and has 63" drivers and 24" x 32" cylinders. It is in the California State Railroad Museum, Sacramento, California.
