The Transbay Joint Powers Authority is seeking input on the planned San Francisco rail extension to the Salesforce Transit Center via a short survey. The survey closes Thursday.

The Downtown Rail Extension (DTX) will extend Caltrain commuter rail from its current terminus at Fourth and King streets to the new Transit Center. It will also deliver the California High-Speed Rail Authority’s trains to the Transit Center.

The 1.3-mile rail extension (1.95 miles of total construction length) will be constructed principally below grade using cut-and-cover and mined tunneling methods underneath Townsend and Second streets.

The project includes an underground station at Fourth and Townsend streets, six structures for emergency exit, and ventilation along the alignment, utility relocation and rail systems work.

MTC has provided more than $300 million for the $4.5 billion Transbay Transit Center project.
