Dublin/Pleasanton Extension Project
Responsible for the preliminary design of all systemwide elements of the approximately 14 mile Dublin/Pleasanton Extension Project (DPX), now in operation. This included bulk power supply, traction power, train control, communications, and fare collection equipment. Continued with final systems design, testing, and startup as a subconsultant to the Bay Area Rapid Transit Consultants (BATC).

East Dublin/Pleasanton Station Project
Wong was responsible for final design of systemwide elements, power distribution, and lighting for this award winning station. The systems design for the partially underground station provided some unique challenges. The routing of 34.5 kV ductbanks and train control and communications ductbanks and cables required special manholes and ductbanks to coordinate with the elevation changes and piling of the bridge abutments integral to the station. Wong designed all systems facilities to support station communications, ticket agent booths, train control room, and fare collection equipment.

East Dublin/Pleasanton Station Parking Lot Civil Design
Wong was responsible for civil design of a 3,000-space parking lot, storm drainage for station and parking lot, and a new 8-foot by 6-foot reinforced concrete box culvert (varied in sized at certain locations). Wong provided the structural design of the concrete box culvert which was a major structure extending over 400 feet through the north parking lot. Wong also coordinated with various county water and storm drainage agencies.

Bay Fair Tie-in Project
Considered to be the single most complex tie-in on the 28-mile East Bay Extension, the Bay Fair Tie-in designed by Wong permitted cutover without service disruption. Wong designed systemwide ductbanks, dc feeders, and contact rail to permit staged tie-in of the Dublin/Pleasanton Extension to the existing Fremont line. This required extensive and methodical coordination with train control modifications, new traction power gap breakers, and wayside communication cabling including extensive coordination with BART operations and maintenance staff.

Pittsburg-Antioch Extension
Involved in the alternative analysis and final design of the BART Pittsburg-Antioch Corridor Extension (PAX). Wong was responsible for various systems including traction power, train control, signaling, communications, fare collection, and yard and shop facilities.

West Pittsburg/Bay Point Station Project
Wong was responsible for final design of systemwide elements for the station on the Pittsburgh-Antioch Extension (PAX). These elements included CCTV, fare collection, Station LAN, public address, provisions for train control cables, and station alarms.

A related 2-mile long, line section was designed adjacent to the station. The line section included tail tracks at the PAX extension terminus. Wong designed all systems elements to support the wayside train control and communications equipment. The design included routing of cables for the interlocking, cabling to wayside signal aspects, raceways and cabling for dc feeder cables, and provisions for routing of 34.5 kV subtransmission cables. The work also included an underground 1000 Vdc gap breaker station and associated ductbanks for dc feeders at the crossover adjacent to the tail tracks.

Contact Rail Design for the Extension Projects
Responsible for the contact rail design for the entire 28-mile BART East Bay and Colma Extensions Program (CSX). The contact rail design included staging plans and tie-in requirements for the PAX Extension at Concord Station, the DPX Extension at Bay Fair, and the CSX Extension's tie-in to the Daly City yard lead tracks. Wong successfully completed the contact rail design involving tie-in without disrupting service to the existing line.

Communications and Central Control Projects
Designed the fiber-optic cable communications network for the BART East Bay Extension Program. The project included the design of a fiber-optic communications backbone network and design of a SONET wide area network with interfaces to Central Control.

Automatic Fare Collection System
As a subconsultant to the Bay Area Transit Consultant (BATC), Wong was responsible for the Revenue Control System, aka. Automatic Fare Collection, for BART Extensions Program. Wong's responsibilities included preparation of design criteria, procurement documents, preparation of procedures for negotiated procurement, and bid analysis and evaluation. The BART revenue collection system is a stored-fare credit/debit system which uses ticket vendors, fare gates, addfare machines, money changes, and ticket readers as the principal equipment. Statistical and performance data from the fare collections equipment are collected from a data acquisition system consisting of a computer at each passenger station and a master computer at Central Control.
