Upon returning passengers to the last stop at the Robert J. Cabral Station in Stockton, the trains continue north approximately one mile to the ACE Rail Maintenance Facility located E. Alpine Ave. The San Joaquin Regional Rail Commission (SJRRC) who is the agency who oversees the ACE service, has contracted Herzog Transit Services Inc. (HTSI) who clean, perform maintenance and prepare the cars for following day's passengers.
In 2019, the facility opened it's gates as the boarding and deboarding location for area school groups who chose to ride the ACE train to field trips throughout the Tri-Valley and Silicon Valley areas.
The maintenance facility was designed to incorporate a variety of sustainability features. More than 1,100 solar photovoltaic panels provide 20% of the building’s power (260 kilowatts), specialized window shades follow the sun, electric power usage is monitored in real-time, and a 102,000-gallon rain harvest tank is part of the reclaimed and reused water system. The facility was the first in the country to achieve LEED Silver certification from Leadership in Energy & Environmental Design and was awarded 2015 Outstanding Project of the Year, Sacramento Chapter of the American Society of Civil Engineers (ASCE).
