Vintage 1948 double-end PCC streetcars Nos. 1006 (left) and 1011 pass just south of the Ferry Building during E-line training, July 1, 2015
Think of it as a dress rehearsal: double-ended historic streetcars cruising the length of The Embarcadero, running along both the F-line tracks (from the Wharf to the Ferry Building) and the N- and T-line tracks (from Folsom Street past AT&T Park and on to the Caltrain Depot at Fourth and King Streets.
With only an operator and Muni training staff on board.
These streetcars are getting ready for the formal launch of the long-awaited E-Embarcadero vintage streetcar line, which begins weekend operation on Saturday, July 25 August 1, from 10 a.m.-7 p.m. Seven-day operation will follow early in 2016.

So if you see these historic streetcars with the “Training Car” or “Not In Service” signs along The Embarcadero, now you know why.
Give them a friendly wave!
