Capitol Corridor trains are state-funded and owned, and Amtrak equipment and employees are contracted to operate the system and maintain equipment. Union Pacific owns all trackage on this line and therefore engineers and conductors must comply with Union Pacific procedures if something abnormal were to arise. Union Pacific dispatch in Omaha, Nebraska is in contact with Capitol Corridor engineers at all times, except between CP Coast and San Jose Diridon, where Caltrain dispatch is in effect. All Amtrak California systems (Capitol Corridor, Pacific Surfliner, San Joaquin) operate under reporting mark CDTX (California Department of Transportation). CDTX operates a roster of F59PHIs numbered 2001 through 2015. (2001 is photographed above in Sacramento, CA). These old Electro-Motive Division diesels are being replaced by diesel-electric SC-44s, numbered 2101 to 2106, built by Siemens in Florin, California. Bi-level "California Cars" are used on all Capitol Corridor services. CDTX operates push-pull services, utilizing cab cars on all eastbound services. Numbered 6961 through 6965 (newer version) and 8301 through 8314 (older version). Capitol Corridor trains and engineers use the same radio frequencies as Union Pacific, however they are maintained separately. Amtrak has a maintenance facility a few thousand yards north of CP King Street in Oakland, California.
