In November 2012, a joint venture led by Sumitomo Corporation and Nippon Sharyo was awarded a contract by the California Department of Transportation (Caltrans) to build 130 bi-level passengers cars for Midwestern and California service. Under the terms of the contract, which used federal funding, Caltrans would own 42 of the cars for Amtrak California service, while a consortium of Illinois, Michigan, and Missouri would own the remaining 88 for Amtrak service out of Chicago. In August 2014, the states ordered 45 more cars—34 for Midwest service and 11 for California. In mid-2015, a prototype carbody failed a compression test, leading to an indeterminate delay in delivery. As of January 2017, no progress had been made on building the cars, and Caltrans, Illinois, Nippon Sharyo, and the Federal Railroad Administration were in negotiations to extend the September 30, 2017 deadline for spending the federal funding used in the order. Amtrak and Sumitomo would announce later that year of their amended order of 137 Siemens Venture single-level passenger cars to be built by Siemens at their Sacramento plant, with Sumitomo dropping Nippon-Sharyo as the builder. Delivery is slated for 2020–2021.
