BNSF train BNSF S-LPCLBT1-08 passes under the Los Angeles Metro’s A Line (formerly the Blue Line) trackage as it heads to the Port of Long Beach to complete its run from Chicago. This intermodal train, powered by BNSF ET44C4 3837 and Dash 9-44CWs 4144 and 669 (ex-ATSF 669), is nearing the southern end of the Alameda Corridor, a 20-mile (32 km) freight rail "expressway" owned by the Alameda Corridor Transportation Authority that connects the ports of Los Angeles and Long Beach with the transcontinental mainlines of the BNSF Railway and the Union Pacific Railroad near downtown Los Angeles. Ten miles of the Alameda Corridor consists of a triple-track mainline running in a trench below grade, parallel to Alameda Street, to avoid grade crossings. The Corridor is similar to a toll road for the railroads as, being owned by neither BNSF or UP, they pay a fee to operate upon it. (Compton, California – March 12, 2022)
