West Portal is a busy station which
marks the transition between surface running and the much quicker
underground portion of Muni into downtown. Trains emerging
into the daylight here on the K-Ingleside, L-Taraval and M-Ocean
View lines have come through the full Muni Metro subway and then the two and
one quarter mile Twin Peaks Tunnel.
Once outdoors, the K-Ingleside and M-Ocean
View lines continue more or less straight beyond in
this view, and L-Taraval turns sharply to the right onto Ulloa
It was common in the earlier years of the Muni Metro subway -- the
era of the Boeing-Vertol car
-- for trains made up of
units from some or all of the three lines to join here inbound, or to uncouple,
There are additional photos from the area in the sections devoted to
the K and M lines, and to L-Taraval.
