Vehicle Procurement & Engineering

Advancing the Fleets That Keep Transit Moving

Transit vehicles are where infrastructure connects most directly with the passenger experience. As agencies replace aging fleets and introduce new propulsion, accessibility and onboard technologies, vehicle procurement has become a complex, long-term undertaking that requires careful coordination from initial requirements through manufacturing, testing and entry into service.

STV helps transit agencies plan, procure and implement vehicle programs that improve reliability, performance and the rider experience. Our experience spans commuter and heavy rail, light rail and streetcars, buses and emerging zero-emission technologies, giving our teams a broad perspective on how vehicles need to perform within the larger transportation system.

We approach procurement as a lifecycle program rather than a single transaction. Our engineers and technical specialists work with clients to define requirements, develop specifications, evaluate designs and manage technical reviews while maintaining oversight as vehicles move into production. During manufacturing, testing and commissioning, we help agencies monitor quality, identify emerging risks and maintain continuity across complex, multi-year programs. Digital information management and disciplined technical governance add greater visibility and accountability throughout the process.

As fleets evolve, STV also helps agencies navigate the transition to new technologies. Our work encompasses fleet modernization, battery-electric and other lower-emission propulsion technologies, charging and supporting infrastructure, systems integration and maintenance considerations. By connecting vehicle engineering with operations, facilities, power and systems expertise, we help clients make fleet investments that work within their existing networks while preparing for future needs.

The goal is a fleet that performs as intended throughout its service life. By combining engineering, procurement strategy, manufacturing oversight and lifecycle thinking, STV helps agencies manage risk, incorporate new technology and put reliable vehicles into service for the communities that depend on them every day.

Our Capabilities in Vehicle Procurement & Engineering

STV supports transit agencies throughout the vehicle procurement and fleet modernization lifecycle:

• Vehicle Engineering and Specifications: Developing technical requirements and specifications tailored to operational needs, performance objectives and applicable industry standards.
• Procurement and Technical Advisory: Supporting procurement strategy, bid evaluation, contract requirements and technical decision-making throughout complex fleet programs.
• Design Review and Systems Integration: Reviewing vehicle designs and coordinating propulsion, communications, controls, safety, accessibility and other onboard systems to support reliable operation.
• Manufacturing and Quality Oversight: Monitoring production, supplier performance and quality to identify issues early and maintain alignment with technical and contractual requirements.
• Testing, Commissioning and Acceptance: Supporting and witnessing testing and validation to verify vehicle performance, safety, compliance and readiness for passenger service.
• Fleet Modernization and Emerging Technologies: Helping agencies evaluate and implement new propulsion, electrification and vehicle technologies while accounting for operational and infrastructure requirements.
• Maintenance and Lifecycle Planning: Incorporating maintainability, asset performance and long-term operational needs into vehicle decisions from the beginning of the program.

What Sets STV Apart

• Lifecycle Perspective: We support vehicle programs from initial planning and procurement through design, manufacturing, testing, commissioning and implementation, helping clients maintain continuity across multi-year investments.
• Vehicles as Part of the System: Our vehicle specialists work alongside experts in rail and transit systems, power, facilities and operations to consider how new fleets will function within the larger network.
• Technical Oversight Where It Matters: Our hands-on approach to design review, manufacturing, testing and quality assurance helps clients identify risks before they affect delivery or long-term fleet performance.
• Experience Across Modes and Technologies: Our work spans rail and bus fleets as well as evolving propulsion and zero-emission technologies, helping agencies navigate modernization without losing sight of reliability and operational needs.
• Focus on Long-Term Performance: We help clients look beyond vehicle delivery to maintenance, reliability, adaptability and passenger experience throughout the fleet lifecycle.
