This late 1950s WP circular, left, indicates that Shell Point was an important customer for the three railroads along the North Coast of Contra Costa County. The 1953 Thomas Bros. map, right, identifies Shell Chemical in West Pittsburg, today Bay Point. More on Ambrose next.

This 1914 map supports the listings in books about the Atchison, Topeka and Santa Fe that Ambrose was a passenger stop 3.5 miles west of Pittsburg until the end of WWI. It was later referred to as “Brose”. Ref: Ref: Weber's CCC 1914 G4363.1914.W4

An east view of the Shell Chemical Plant from Jan. 20, 1951, with the McAvoy-Port Chicago Highway intersection in the lower left corner. The turquoise arrow denotes a set of three trestles for the railroads across a creek, and will be referred to later in SN mileage terms as mile 43 trestle. The orange arrow indicates a cluster of trees.

This agriculture-related map from 1939 indicates the area had been invested in hay and grain. According to Dean McLeod’s “Bay Point”, Shell Chemical built their plant specializing in ammonia production on Ambrose Ranch in 1928. A pictorial review of George Russell aerials of this territory prior to this construction follows. Ref: G4363.C6J1 1939 .C6.

From the east or right side of L182-45, the cluster of trees is now to the west or left border, and everything to the east or right would correspond to the site of the future Shell plant. The total size of the Ambrose ranch has not been determined, but this has to be a part of it, extending to the south as well. The cluster of trestles in the background corresponds to the SN mile 43.5 trestle. Ref: API 578_26_BOX 72

A closer view of what had started as Acme Steel is estimated to have been built in the 1970s based on historicaerials.com and telephone directories. Now occupied by ITW Angleboard, it is the only remaining industry in the East Bay serviced by original SN track, and can only be approached from the west via the SP-SN interchange at McAvoy.

Back on the SN mainline, further to the east was Shell Chemical, here shown in a north-oriented vertical from 1965. The SN spur took off close to the plant, yellow arrow, while the SP spur, now UP, red arrow, originated much further east beyond the SN subway.

Images during the electric era taken from the McAvoy crossing to the east were displayed in the previous section, “Switching at McAvoy with Dave Stanley”. No photographs from the electric era between that location and the Shell Chemical plant spur have been identified. This may be do to no road access between McAvoy and Suisun Ave. as indicated along the orange line in the Thomas Bros. map from 1953.

The SN right-of-way became accessible at Suisun Ave., and this northeast view from Apr. 1941 shows SN 1010 and trailer running next to the SP spur to Shell Chemical. The SN trestle at milepost 43.85 has not yet been covered, but it did not survive into the 1950s as will be shown later.
