The Caltrain Modernization Program includes the electrification of the existing Caltrain corridor between San Francisco and San Jose; the installation of a Communications Based Overlay Signal System Positive Train Control (CBOSS PTC), which is an advanced signal system that includes federally-mandated safety improvements; and the replacement of Caltrain’s diesel trains with high-performance electric trains called Electric Multiple Units.

The $1.5 billion program is funded through a nine-party agreement that leverages local, regional and federal funding to match $705 million in voter-approved high-speed rail bond revenues.

Electrification of the Caltrain corridor requires environmental approval under the National Environmental Policy Act and the California Environmental Quality Act. Through 2013, Caltrain will be updating the project’s initial environmental review and will engage communities in a public planning process to help guide implementation of the project.
