The original right-of-way leading into Tracy from the Bay Area via the Altamont Pass was built back in 1873 by the Central Pacific as part of the Transcontinental Railroad linking California with the East Coast.
Trains traveled in and out of Tracy from the railyards near downtown, along old Schulte Road through the original site of the Ellis coaling station, then curving up toward the foothills to Midway and Cayley, then on to the summit at Altamont.
Today, the old, original right-of-way — with the rails intact — remains in place all the way from downtown Tracy to the intersection of Patterson Pass Road and Midway Road, a few miles past I-580.
Beyond that, the old roadbed, shorn of rails and ties, can be traced up through Cayley to the abandoned S.P. tunnel through the Altamont Hills, then as it winds alongside the former Western Pacific tracks (now the mainline for the Union Pacific and ACE commuter trains) into the venerable town of Altamont — once a key stop, where helper engines joined in to assist heavy trains over the summit, as well as a stop for vehicular traffic on the historic Lincoln Highway.

INSET: A “training train,” staffed by members of Southern Pacific management being taught to operate equipment in the event of a strike, rumbles along Patterson Pass Road near Midway on the way to Altamont in this classic 1994 photograph. The strike never happened, SP merged with UP, and the line was soon abandoned and removed.
Images of how the old right-of-way looked in the Spring of 2011 appear below.
