Equipment Information

Southern Pacific 975 is a heavy freight engine and one of only five American 2-10-2 engines preserved intact. This wheel arrangement was popular around World War I but was later supplanted by 2-8-4 and 2-10-4 engines that were faster and more powerful. While 2-10-2s were called “Santa Fe” types, the SP – a rival to the Santa Fe Railroad – called its 2-10-2s “Decks” despite the fact that “Decapod” typically refers to a 2-10-0. SP 975 was displayed in Beaumont, Texas for several decades until IRM acquired it to prevent the engine from being scrapped.
