Bachmann created a Spectrum series 2-8-0 in 2001. ATSF fans have asked how similar this loco is to the 2507 class consolidations which ATSF inherited from the KCM&O. With the help of Frank Ellington's Steam Locomotives of the Santa Fe, photos of a Hallmark brass model of this loco, the modeling work of Ted York, we will try to answer that question.

About three years before the Orient was sold, 19 heavy consolidated type locomotives were purchased from the New York Central. They were made by the Schenectady and Brooks Plants of the American Locomotive Company in 1907, 1908 and 1910. These engines were fitted with 23x32 piston valve cylinders, 14-inch valves and inside steam pipes. They had 63-inch drivers. The boilers were fitted with wide fireboxes and carried 200 pounds pressure. These engines were numbered 51-69, later becoming the Santa Fe 2507 class. They weighed 215,500 pounds on drivers.

Since the Orient was sold, 14 engines of this class have been equipped with 23 1/2 x 32 cast steel cylinders, designed by Ores Bilge and outside steam pipes. On account of the excessively hot climate in the Southwest, the Orient removed the two steam fountains inside the cab and placed one outside in front. The long single bar valve stem crosshead guide was replaced by self-centered back steam chest head. Also the New York No. 5 air brake was replaced by the Westinghouse No. 6-ET brake.
