The consortium will be responsible for taking the project to the 30% engineering level, supporting cost and scheduling estimates required to demonstrate the integrity of VTA’s management, financial and implementation plans. This will feed into VTA’s application to participate in the Federal Transit Administration (FTA) Expedited Project Delivery pilot programme.

VTA is seeking a $US 1.5bn FTA contribution for the $US 4.7bn project, which is due to be completed in 2026

From the Phase 1 terminus at Berryessa, the extension will run for 9.6km beneath the centre of San Jose before reaching an interchange with Amtrak, Altamont Rail Express, Caltrain and VTA light rail services at Diridon station. The line then continues northwest to a terminus at Santa Clara Caltrain station.

The project involves the construction of an 8km single-bore double-deck tunnel, which will accommodate the two running lines.
