A BNSF northbound from Everett, Washington, passes by Gyproc on the north track of the CN Yale Sub at mile 117.4. This used to be called Liverpool, the northern terminal of the Great Northern Railway from 1891 until the railway reached Vancouver proper in 1904. The train -- 6000 feet long, whose tail-end is in old Brownsville -- will pass the former GNR dock and Royal City mill on its way to Thornton, where it will yard just west of the Port Mann Bridge at old Bon Accord. At right is the south track of the Yale Sub, once the siding at Liverpool.
