The steepest main line which sees regular freight service on the BNSF system is on the Cajon Sub. Between Cajon and Summit Main 3 (the old westbound track) takes the quickest route to Summit. At times this track has a 3% grade, " climbing 3 feet every 100 feet". Only the hottest and or under tonnage trains are permitted on this track.. Sit back and watch Amtrak, UP and tons of BNSF Z9's conquer Cajon Pass.
Enjoy!
