TSE Projects

From Concept to Final Construction, TSE delivers key engineering consulting services for major public transit systems nationwide, a representative sampling of which are described below 

BART: Hayward Maintenance Complex Phase I & II | Hayward, CA

The Hayward Maintenance Complex Projects will increase Bay Area Rapid Transit's maintenance capacity as part of its Fleet of the Future program. The first phase involved acquisition and improvement to four properties on the west side of the existing Hayward Yard for a repair shop, a new component shop, vehicle overhaul shop, central parts warehouse, and a maintenance and engineer­ing shop. TSE engineers were responsible for engineering design services for Traction Power, Yard Train Control and Systems Integration, and design submittals for CCTV, SCADA, Telephone, Access Control, Trunk Radio and PA System.

.

For HMC Phase II, work consists of developing design drawings for the existing BART Hayward Rail Storage Yard and undeveloped land located north of the BART rail storage rack and east of the BART mainline tracks for construction of the East Storage Yard.

BART: Warm Springs Extension | Fremont, CA

The BART Warm Springs Extension added 5.2-miles of new track from the existing Fremont Station, southward to a new station in the Warm Springs District in the City of Fremont. Transit Systems Engineering was a major subconsultant on the General Engineering Consultant Team providing overall design and design management of the extension (including preparation of bid documents) and system design. TSE provided support, including: developing the train control and communications interface systems, providing ATC system block design and design services for BART communications systems. TSE also provided design and other support services during the construction phase of the project.

SFMTA: Integrated Systems Replacement (ISR) & Human Machine Interface Projects | San Francisco, CA

Along with the implementation of a new Transportation Management Center (TMC), many of the existing communication systems in the current Control Center and existing Metro subway are being upgraded or replaced. The SFMTA Metro Subway includes nine underground passenger stations. TSE is responsible for design deliverables for the replacement systems which include: communications systems, construction management/support services. TSE also collaborated with SFMTA to design and implement a new Integrated Human Machine Interface (IHMI) system for its new Transportation Management Center (TMC). The new TMC is a state-of-the-art facility that replaces the SFMTA’s outdated Operations Control Center (OCC) as its primary control center and will combine all of SFMTA’s control functions, which are currently dispersed across the city.
