SL-SF Class 1018 4-6-2 Streamlined Steam Locomotive
Originally delivered as Class 1015 from Baldwin Locomotive Works in 1910, these were some of the first locomotives with superheaters in North America. The class was rebuilt in the late 1920s and early 1930s. In 1939,  three of these rebuilt  locomotives were re-designed to enhance the Frisco's "Firefly", a new streamlined train between Kansas City, Missouri, and Oklahoma City, Oklahoma, via Tulsa, Oklahoma.

According to Frisco publicity, the locomotives were also used on the "Black Gold" passenger train. A number of changes were made to the previous design that had featured smaller cylinders and higher boiler pressure, larger drivers, a larger tender, more weight on the drivers, and conversion to burning oil. Numbers 1018 and 1031 were fitted with Walschaert valve gear,  while No. 1026 had Baker valve gear.

The streamline shrouding featured a bullet nose, a flared stack, and a thick valance over the open running gear. A broad stripe of color along the valance and the tender was lettered "Frisco Lines." The new look gave the locomotives somewhat of a resemblance to a shark.

All three locomotives kept their streamlined casings the remainder of their careers with the Frisco. Number 1026 was the first of the three to be retired from service on May 31, 1949, with Number 1031 following on October 4, 1949. Number 1018 continued in use until May 22, 1950.
