A comparison of three aerials and map notes the position of the west end of the double track by the black arrow. In the 1968 aerial, the arrow is for comparison only as BART is all double track here; note the footbridge over BART. Full Ref.: USDA AAA Western Division, BUU 280-64 from Jul 25, 1939; Full Ref.

A definitive image of the switch track initiating the double-track section from the west end could not be found, but its origin is implied by the added catenary poles to the east of the block signal in this northeast image of SN 661 with freight at the Lee Lane grade crossing, circa 1952.

A summary of the key portions of the double-track section using the 1958 aerial and the Board of Equalization map. The black arrow indicates the west end of the double-track section seen in L103-30, the red arrow the switch track seen in L103-40, and the blue and yellow arrows the continuation of the southern-most track as the Walwood branch take-off seen in L103-45. The green arrow may be pointing to a single car on the Walwood take-off.
