As Don-In-Napa has reported, the Union Pacific property on the north side of Napa Junction Rd is being graded for future development. Recently, a building was built along side the Lomburd yard where there is a team track and someone receives copious inbound gondolas of rebar type stuff. These images show that area.
The property now to be developed is situated next to an old long-abandoned right of way that was once part of a kidn fo teardrop-shaped wye. In these pictures some of the features of this old ROW are featured, as well as the Cal Northern.
In the pic below the Lombard turn is just about to pass the west switch where the west leg of the teardrop kind of wye was. You can see some ROW fencing and the fennel growing in the old ballast and perhaps an old culvert. All of this in the right bottom corner of the picture. The abandoned track would have been very nearly symetrical with the track which the cars are on in the pic, forming a teardrop or oval.
In this picture the Lomburd turn is on the north leg of the wye which was put in when they abandoned the older configuration. The tracks in the foreground are the east leg of the old teardrop wye, now the south leg of the current more conventional shape wye. The photographer is standing on the west leg of the old teardrop wye.
In this last pic you can see one of the old timey "Look Out For the Cars" crossbuck posts that has been recycled as a mailbox post.
