Atchison, Topeka and Santa Fe Railway 3751

Locomotive number 3751 is a steam engine built in 1927 with eight driving axles and sixteen powered wheels in Los Angeles, California. It weighs roughly 220 tons (490,000 pounds) without the tender and measures over 100 feet (30 meters) in length including the coal car.

It left the factory in Philadelphia in the late twenties and crossed deserts between Kansas and southern California for decades. After retirement in the early fifties it stood on display in a park until rail enthusiasts brought it back to working order in the nineties.

The engine bore the name of a California mountain range and pulled trains across the longest routes of the company for more than two decades. It now stands as a working monument to the golden age of rail travel in the Southwest and remains cared for by volunteers.

Visitors can view it up close during special runs or at public events, with guided tours often offered through the engine house. Because of its size and weight, it remains housed in a specialized depot when not in operation.

It was the first example of its wheel arrangement in the entire fleet and reached speeds over 100 miles per hour (160 kilometers per hour) on its fastest runs. Despite its age, it still operates occasionally on short stretches and draws crowds at crossings along the route.
