The story

How Tres Pinos came to be

From Wikipedia’s history of Tres Pinos.

Read it all →

The original settlement of Tres Pinos was located 5 miles (8.0 km) south of the current town. The Southern Pacific Railroad reached what they called Tres Pinos station on March 12, 1873, running two passenger and two freight trains a day. In 1874 the original settlement of Tres Pinos was renamed to Paicines. The railroad was planned to run further south to Coalinga and Los Angeles, though Los Pinos would end up as the end of a minor branch as the main lines were built elsewhere.

In its heyday the town was not only the end of the railroad line but was also a stage coach stop. There was a Southern Pacific Hotel, rodeo grounds, grain barns, corrals, and many saloons, restaurants and even a brothel.
