to the design to make the vehicle more suitable for corridor services with frequent stops. One significant difference is that the Surfliner and California Car have two sets of automatic doors on each side instead of only one manually operated door on the Superliners, which speeds up boarding and alighting considerably. Additionally, Surfliner and California Car coaches are equipped with higher-density seating and bicycle racks to permit transport of unboxed bicycles. Consists on the San Joaquin, Capitol Corridor, and Pacific Surfliner routes usually include between four and six cars, with one locomotive and a cab control car on the rear end. Superliner I rebuilds In 2007, Amtrak California paid for the repair of seven wreck-damaged Superliner Coaches owned by Amtrak in exchange for a six-year lease, intended to quickly add capacity on busy Capitol Corridor and San Joaquin trains. Four of the cars have been painted to match the "California car" livery, and three have been painted to match the "Surfliner" livery. Each car also has the current Amtrak logo on the middle left side of each car. Superliner I/II coaches from Amtrak's national fleet are used on some consists due to shortages of inter-city "Surfliner" & "California cars." Comet car single-level trainsets Increasing ridership on the San Joaquin led Amtrak California to purchase 14 Comet IB rail cars from NJ Transit in 2008 for $75,000 per car. Caltrans paid approximately $20 million to have these former commuter cars refurbished and reconfigured to serve as intercity coaches at Amtrak's Beech Grove Shops. Caltrans has also paid to lease and refurbish 3 Horizon dinettes (used as café cars) and 3 Non-Powered Control Units (old F40PH locomotives converted to serve as a cab/baggage car). Siemens Venture single-level trainsets In November 2017, the California Department of Transportation announced that it would be ordering seven Siemens Venture trainsets through its contractor Sumitomo Corporation. The states had initially contracted Sumitomo, which in turn subcontracted with Nippon Sharyo, to build the Next Generation Bi-Level Passenger Rail Car, but a prototype car failed a buff strength test in August 2015. After the test failure, Sumitomo canceled its deal with Nippon Sharyo, and turned to Siemens to be the new subcontractor. The cars are being built at the Siemens factory in Florin, California and will be hauled by California's existing fleet of diesel-electric locomotives. California's trainsets will be used exclusively on the San Joaquins service and will consist
