Atchison, Topeka & Santa Fe Berkshire Type Locomotives

The Atchison, Topeka & Santa Fe Railroad bought fifteen "Berkshires" type locomotives from the Baldwin Locomotive Works in 1927. These locomotives were designated as Class 4101 and assigned road numbers 4101 through 4115. The AT&SF was the only western railroad to have purchased new 2-8-4s.

These Class 4101 "Berkshires" had 63" diameter drivers, 27" x 32" cylinders, a boiler pressure of 220 psi with a resultant tractive effort of 69,200 pounds (number 4115 had a 250 psi boiler pressure, which raised its tractive effort to 78,685 lbs). Each of the fifteen locomotives weighed 393,000 pounds.

The AT&SF also bought seven used "Berkshire" type locomotives from the Boston & Maine during the closing months of World War II.

There are no surviving AT&SF 2-8-4 "Berkshire" type locomotives
