Fresno Subdivision

Mostly built by the Southern Pacific Railroad in the 1870s, the line traverses the San Joaquin Valley on a northwest to southeast alignment.

[1] From its interchange with the Martinez Subdivision in the north, it runs south through Elk Grove, Lodi,[1] Stockton,[2] Manteca,[3] Modesto, Merced,[4] and Madera before entering Fresno.

[citation needed] Amtrak and the Altamont Corridor Express operate passenger trains over the northern segment of line.

The branch line from Lathrop reached Goshen in August 1872, Delano in July the following year, and had extended past Bakersfield to Caliente in 1875.

Ten miles (16 km) of the line between Ceres and Turlock is expected to be double-tracked as part of the Altamont Corridor Express expansion.
