The original service used two trainsets, each with 4 bilevel coach cars, for a total seated capacity of 1120 passengers in each direction daily. In September 1999, the service reached 1000 daily riders per direction, resulting in many trains running at capacity. On February 21, 2000, a morning short turn between San Jose and Pleasanton was added using an existing trainset, giving Pleasanton and Fremont a third inbound train to alleviate the crowding on the two earlier trains. The trip was added after ACE funded $3 million in track improvements to reduce conflicts with Union Pacific freight trains and Amtrak "Capitol Corridor" trains.
