Design and analyze wayside signal systems, interlockings, switch machine systems, train detection systems, vital and non-vital logic, and highway-rail grade crossing warning systems in accordance with industry standards and client requirements.
Prepare engineering calculations, technical specifications, bills of materials, cost estimates, design reports, and other technical documentation required to support project delivery.
Coordinate signal system interfaces with traction power, communications, SCADA, OCS, train control, track, civil, roadway, station, and utility systems to ensure successful multidisciplinary integration.
Support the design, integration, testing, and commissioning of conventional signaling, Positive Train Control (PTC), Communications-Based Train Control (CBTC), Automatic Train Protection (ATP), and Automatic Train Control (ATC) systems.
Support project planning and execution activities, including scope development, resource forecasting, schedule management, technical risk assessment, proposal preparation, fee development, and business development efforts.
Conduct field investigations, site inspections, diagnostic reviews, testing, commissioning, cutovers, and construction support activities, including responding to RFIs, reviewing submittals, and supporting revenue service implementation.
Interface with clients, railroads, contractors, regulatory agencies, and project stakeholders while ensuring compliance with FRA, FTA, AREMA, MUTCD, railroad owner standards, and applicable safety, quality, and environmental requirements.
Lead factory acceptance testing (FAT), site acceptance testing (SAT), commissioning, cutover planning, and revenue service implementation activities for signal, train control, and grade crossing systems.
Develop signal design criteria, standards, specifications, engineer’s cost estimates, and evaluate alternative technical solutions and value engineering opportunities to improve safety, reliability, constructability, and lifecycle costs.
Support and coordinate highway-rail grade crossings, traffic signal preemption and transit signal priority (TSP) systems, while interfacing with FRA, railroads, transit agencies, roadway authorities, utility owners, and other project stakeholders throughout project development and implementation.
