This is the view west back toward the BNSF Richmond Terminal along the Siberia Lead. The track does a nice little jog before connecting to the RPRC trailing switch. From a design perspective, I looks like the switch was positioned to connect to the RPRC, then the Siberia Lead jogs bck into alignment on its way east.
Note that this BNSF track was laid with continuous welded rail about 18 months earlier to allow BNSF stack trains to continue from Richmond to the Port of Oakland where BNSF has built a new intermodal facility. I nearly fell over the first time I saw 4 BNSF Dash-9's in HII pulling a long string of stacks along this lowly trackage. It looked lost!
