The 12th street station in Oakland has three tracks, two on the upper level for Pittsburg/Richmond bound trains, and
the lower track is for south bound trains for Fremont, and Millbrae.
This is from 3/2008, from Trevor Carrier. Here is the Wye Intersection
the 12th Street Station. This
is where the Millbrae-Richmond (right tunnel), and Fremont-Richmond
(left tunnel) lines come together. The Baypoint/Pittsburg line is on the
opposite side of the platform.
