RSE provided engineering and construction support services for the track and signal rehabilitation of the VTA’s downtown transit mall.
Scope of Services
The engineering work included trackwork, special trackwork, grade crossings, signals, and communications with trackwork and signaling upgrades as two major components for the rehabilitation.
RSE was the primary engineering consultant on this project for the preparation of the complete set of construction documents including plans, construction cost estimates, and specifications (PS&E). Trackwork design included site plans, track alignment and profile, typical track sections, track demolition, track construction details, track wire and signal circuit replacements, and special trackwork. Engineering support included technical specifications, construction cost estimates, schedule, and structural calculations for track slab reinforcements.
The project consisted of replacing embedded track, reconstructing roadways, reconstructing special trackwork, upgrading signal systems, and installing new signal and power.
The key features for signal-related work included replacing existing vital and non-vital relay logic with solid state VHLC microprocessor controller, installing new Hanning & Kahl HCS-V bi-directional TWC communication equipment, installing solid state GE HSC switch controllers, installing new signal heads with 8 3/8” LED aspects, preparing VHLC vital and non-vital application software programs, and providing control from the signal locations to the Operations Control Center (OCC).
