instruction: From this passage, extract the names of the three Amtrak California routes and separate them with commas.
context: Amtrak California utilizes a livery and logo that is different from the standard Amtrak colors. All state-contracted Thruway Motorcoach and state-owned locomotives and passenger cars, with the exception of equipment used on the "Pacific Surfliner" route, are painted in the "California Colors" of blue and yellow. Each permanently assigned passenger car is named after a geographical feature of California.
  
  The "Capitol Corridor" and "San Joaquin" trains are the two routes most identified with the Amtrak California image, since they extensively use "California Colored" equipment. The other state-supported rail route, the "Pacific Surfliner", uses a unique blue and silver paint scheme that is different from the other Amtrak California-branded trains.
  
  The NPCUs that operate on the Capitol Corridor and San Joaquin are painted differently from the locomotives, as they are painted in the old "Caltrain" locomotive livery, with an Amtrak California and Caltrans logo on the sides. The single level cars, both the Comet cars and the Horizon dinettes, have three stripes closest to the boarding doors, orange, blue and green, which resemble the NJ Transit livery that was previously used on the Comet cars.
