A short Union Pacific westbound freight has attained the top of Cajon Pass at appropriately named "Summit" on July 14, 1992. The freight has been routed down the steep South track (3 percent). The green "clear" signal on the eastward signal for the North track confirms a train is coming up that route--two miles longer, but 2.2 percent. A third main was added a few years ago. BNSF estimates the three mains are capable of handling as many as 150 trains a day. The speed board on the left (55 for passenger, 50 for freight) confirms the line up the east side of the pass is much straighter and faster.
