Overview of the ATSF SD26

Discover the EMD SD26, a powerful diesel locomotive that served the Atchison, Topeka and Santa Fe Railway.

Originally built between 1958 and 1963 by EMD, these locomotives were a significant part of American railroading. A notable refurbishment program by ATSF from 1973 to 1978 enhanced their capabilities for modern operations.

With a top speed of 89 km/h and a robust Co'Co' wheel arrangement, the SD26 featured an EMD 16-567D3 prime mover generating 1957 kW of power. Its impressive tractive effort of 360 kN made it suitable for heavy hauling. This locomotive boasts a standard gauge of 1435 mm, aligning with widely used track specifications.
