Locomotive and Freight Car Fleet
St. Croix Valley Railroad owns locomotive EMD GP9 lettered SCXY 1363.
The SCXY 1363 is now black with a yellow cab face and side trim (separated by a red stripe), recalling the Northern Pacific Railway paint scheme commonly found on later NPRY diesels (shortly before the 1970 BN merger). The words "St. Croix Valley" are visible on the long hood. The paint scheme was previously green with yellow striping. SCXY 1352, an EMD GP8, is also painted in the same fashion as SCXY 1363. In 2014 in the line added two SD40M-2's (SD45 bodies). SCXY 1326 and then SCXY 1325 were acquired to help with additional traffic. Both engines were painted into the SCXY paint scheme by the WSOR paint shops in Horicon Wisconsin. As of 2022 SCXY 1352 has been scrapped at ILSX in Bethel MN due to generator issues.
