In 2007, BART ran a beta test of Wi-Fi Internet access for travelers. It initially included the four San Francisco downtown stations: Embarcadero, Montgomery, Powell, and Civic Center. It included above ground testing to trains at BART's Hayward Test Track. The testing and deployment was extended into the underground interconnecting tubes between the four downtown stations and further. The successful demonstration provided for a ten-year contract with WiFi Rail, Inc. for the services throughout the BART right of way. In 2008, the Wi-Fi service was expanded to include the Transbay Tube. BART terminated the relationship with Wi-Fi Rail in December 2014, citing that WiFi Rail had not submitted an adequate financial or technical plan for completing the network throughout the BART system.
