This is actually the BNSF Siberia Lead crossing both Harbour Way South and Wright Ave. It is an unprotected crossing but for the most part, Marina Way is a pretty quiet road. The BNSF crews often throw off red flares from the lead unit to alert motorists when the crossing is blocked.
This view is looking east along the Siberia Lead. BNSF removed the small three track yard that was here this year. The BNSF used to marshall a few cars for switching the spurs that branch off the Siberia Lead. That switching is now performed by the RPRC so BNSF pulled up the rails. The switch has since been removed too and is currently sitting to the right of the track.
In the summer of 2005, I watched a BNSF switcher shuffling cars here but never took any photos. Google earth still shows the yard shown in this picture.
