SACRAMENTO, Calif. (AP) — Amtrak and the California High-Speed Rail Authority said Friday that they canceled a joint agreement seeking companies to build high-speed trains for them, a proposal billed as a way to save money and lure advanced train manufacturing to the United States.

The agencies said their needs are too different and manufacturers are not yet ready to build trains that can run on both Amtrak’s 100-year-old rail lines and the high-speed corridors planned for California’s system.
