 The crossing was the intersection of the tracks for the former ATSF and former Southern Pacific (SP) railroads.Southern Pacific is now Union Pacific and the Atchison, Topeka and Santa Fe Railway is now BNSF, and both the UP and BNSF still utilize their respective's predecessor's tracks.The Union Pacific tracks runs east-west at the crossing while the BNSF tracks operate north-south (the BNSF tracks eventually head west to Los Angeles and Long Beach, parallel to the UP tracks).
