On January 6, 2003, ACE introduced the Stockton Solution Shuttle, allowing Stockton passengers to use the ACE trip which terminated at Lathrop/Manteca. The trip was extended to Stockton on August 1, 2005. At that time, service to Santa Clara was suspended to allow for the construction of a second platform and pedestrian tunnel at the station. At this time, three Amtrak Thruway Motorcoach trips connecting to the "San Joaquin" - one to San Jose and two to Stockton - were open to ACE riders.
