SN track east of Dozier was abandoned because of construction of the Sacramento Deep Water Ship Channel. If the track had not been abandoned, a very expensive railroad bridge would have been required for SN track to cross the ship channel.

SN received trackage rights on SP to Canon so it had access to its own line. At one time a deepwater port was proposed for the Sacramento River near the SN line. The old SN line in Solano County was maintained for many years with almost no traffic other than an occasional car to or from Rio Vista Junction so it could serve this port in the future.

When it became clear that this port never would happen, UP donated the SN right of way to the Western Railway Museum that bought the track for salvage value. This track today is not legally abandoned but is embargoed.

The line extension ends where it crosses Birds Landing Road about 1/4 mile from downtown Birds Landing.

Western Railway Museum owns 4 acres of land adjoining the track at Molena. This land probably is big enough to allow a loop here however some museum "purists" were opposed "because SN never had a loop there."

About 1/4 mile west of Molena is a burned out trestle. Restoring the line beyond Molena would be very expensive to replace the trestle although track is mostly intact as far is Fire Engine Road where a very long trestle went across salt marsh.
