The SAP operated comparatively light motive power, including Americans, moguls, ten-wheelers, and consolidations. It acquired a number of them second-hand from the Pittsburgh & Lake Erie R.R., from the Columbus, Hocking Valley & Toledo R.R. and from other lines. Three former El Paso & Southwestern 2-10-0s became SP Class D-1. Some SAP locomotives survived on the T&NO into the 1950s.

The data in the roster is sorted by wheel arrangement and by SP number (by SAP number, if off the road by 1925). If an engine had more than one number, the numbers are listed in reverse order, and the latest is shown first. All are described by the SP's 1904 "Official Classification" (wheel diameter, cylinder size and weight on drivers). In addition, those that joined the GH&SA have the 1913 "Nominal Classification" (letter and number). A list of abbreviations follows the roster.

Locomotive Roster

The roster is accurate as of a half century ago, because I extracted the data from a 1853-1955 SP roster published in 1956 by The Railway and Locomotive Historical Society. (See Source at the foot of this page.) Please email any corrections or comments.
