 The line initially ran on weekends only, but expanded to weeklong service in late April 2016.The initial routing of the line is nearly identical to the 32 Embarcadero bus line, which was discontinued after the F Market & Wharves line began operating along the Embarcadero in 2000.It runs the length of the Embarcadero and San Francisco's segment of the Bay Trail, along pre-existing track used by the F Market & Wharves historic streetcar as well as the N Judah and T Third Street Muni Metro lines and previously unused track bypassing Market Street subway's Embarcadero portal.
