Here's a collection of Google Earth trackmaps for you San Francisco Bay Area historically-inclined types. Scope is San Pablo to San Leandro, covering all the freight railroads. There's also a supplemental section with circa 1927 transbay passenger commute lines--Key, SP's electric lines, and SN.

Major thank you due to AP posters OPRRMS, Dr. Zarkoff, Stash, Bill Root, and others for sharing their knowledge on this subject. Without your help this would not have been possible.

Here's a view of downtown Oakland with the WP in orange juxtaposed against, or under really, the 3-D buildings layer.


The 17 zone(?) in Berkeley. There's tracks in a couple of spots remaining in this zone today. I wonder when the last car rolled off this zone?



ATSF's Oakland District running through Berkeley toward Oakland. Look at all that SP trackage in green on the right. All gone now except for the main lines and National Starch.


WP's shops area at Oakland.


Here's the OTR in yellow and purple. Yellow denotes joint switching facility, in this case shared with the SP. Red is the Oakland Army Base railroad and blue is the Oakland Naval Supply Center's railroad.


Here's an overview of the transbay passenger maps. There's also a 1931 aerial mosaic that in places has great detail.
