Wong has taken a dynamic role in the management of design, construction, and procurement of both new and retrofit projects for the Santa Clara Valley Transportation Authority (VTA). These projects include such projects as communications retrofit, traction power sectionalization, signal priority, substation procurement, and substation retrofit projects. These projects include:

Communications Retrofit Project
The Guadalupe Corridor, VTA's starter line, opened in 1987 had an outdated communications system. It therefore required enhancements which included communications retrofits at 34 stations and 15 substations, including the installation of Local Area Networks at stations to provide data communication between station SONET OC-3 nodes and station equipment including new VMBs, TVMs, and SCADA PLCs.

As prime consultant , Wong was responsible for the preparation of plans, specifications, and cost estimates for the 18-mile Guadalupe Corridor, 6-mile Tasman East Corridor, and Younger Maintenance Facility. Wong's management of construction staging and cut-over requirements for this retrofit project ensured no disruption to train service during the construction and cut-over from the existing T1 system to the new OC-3 SONET fiber optic system. The cut-over was especially critical since modifications to central SCADA software were implemented in stages as groups of passenger stations and substations were cut-over to the new communications backbone.

Traction Power Sectionalization Project
As part of the Rail Design Consultant Services Project for VTA, Wong prepared the design of a major renovation to the sectionalization for the catenary along 18-miles of double track.

Traction Power Substation Procurement Project
The Traction Power Substation Procurement Project required Wong to develop plans, specifications, calculations, and cost estimates for a Traction Power Substation Procurement Contract. This procured traction power substations (TPSS) for VTA's Vasona and Hostetter/Capital Extension Projects.

Traction Power Substation Retrofit Project
In order to support the demand for power, VTA engaged Wong in the development of contract documents for the procurement of new dc switchgear consisting of five dc circuit breakers, of which three will feed the existing line and two will feed the Vasona Extension.

LRT Signal Priority Project
Wong was responsible for an analysis for VTA's LRT signal priority project. The purpose was to reduce LRT delays and lessen the impacts of LRT operations on vehicular traffic in street running areas. These included improving traffic signal coordination, utilization of all levels of traffic signal controller priority, and street modifications.

Testing/Startup
Wong was responsible for managing the testing & startup and rail activation of the 6-mile Tasman West Extension.

Design Criteria and Standard Drawings
Wong was responsible for the review and update of all systems and civil, track, and structure design criteria and standard drawings for VTA.
