Altamont Commuter Express service commenced operations with Stockton as its terminus in 1998, and the "San Joaquin" started service here the following year. In 2001, the San Joaquin Regional Rail Commission (SJRRC), which provides ACE, purchased the old depot for $236,000 (equivalent to $ in adjusted for inflation). Within a year, plans were drawn up for a full $6.5 million restoration that was completed in 2003. The majority of the funds came through “Measure K,” a local voter-approved ½ cent sales tax dedicated to transportation improvement projects.
