ATSF 3000 class 2-10-10-2. The forward section of the boiler is a primitive superheater and feedwater heater. In 1911 and 1912, the Atchison, Topeka and Santa Fe Railway modified ten 2-10-2 Baldwin -built locomotives into a new 2-10-10-2 configuration dubbed the 3000 class.

The ATSF 2-10-10-2's, #3000 class locomotives, were the largest locomotives in the world from 1911 to 1914. Despite being good for helper service, they could only go 10 to 15 mph (16 to 24 km/h) before losing steam, resulting in the locomotives being converted back into 2 …

Feb 10, 2010 · But before they shucked their oddball dress, says Dan Watson's email of 10 May 2016, one of them got into the movies: "Regarding the AT&SF 3000 class 2-10-10-2 locomotives, the 3001 appeared in the theatrical film "The Hazards of Helen" Episode #3: "The Leap from the Water Tower" (1915) as available on youtube ..."

Jan 8, 2025 · ATSF 2-10-10-2 #3000 - Atchison, Topeka & Santa Fe Description: Ten massive locomotives were constructed by ATSF Shops in 1911-12 by joining two 2-10-2 units together with a low pressure engine supplied by Baldwin.

Summary: These two photographs show the Atchison, Topeka and Santa Fe Railway Company's steam locomotive #3000. This "Mallet" type locomotive, built in the ATSF shops in Topeka, Kansas, was equipped with a Jacobs-Shupert non-explosive fire box.

The 2-10-2 wheel arrangement evolved in the United States from the 2-10-0 Decapod of the Atchison, Topeka and Santa Fe Railway (ATSF).

In 1903, the AT&SF asked Baldwin Locomotive Works then known as the Burnham, Williams & Co to build it several 2-10-0 locomotives with a pair of tailing wheels that could be used to guide the drivers when the locomotives were operated in reverse.

In order to explore the extreme limits of the Mallet principle, the Atchison, Topeka & Santa Fe developed the class 3000 in 1911 with the wheel arrangement 2-10-10-2 and a weight of 309 short tons. The goal was to be able to pull 2,000-ton trains with just one locomotive over gradients of 1.2 percent in Arizona.

Only two classes of 2-10-10-2s were ever built -- Santa Fe's 3000 class and Virginian's AE class. The first 2-10-10-2s were constructed in 1911 by the Atchison, Topeka and Santa Fe Railroad. They were built out of existing 2-10-2s with new front engines and tenders from Baldwin.

In 1911 and 1912, the Atchison, Topeka and Santa Fe Railway modified 10 2-10-2 Baldwin-built locomotives into a new 2-10-10-2 configuration dubbed the 3000 class. They were the largest locomotives in the world from their introduction until 1914.
