LA Metro's Division 14 Light Rail Vehicle O&M Facility

Vehicle Operations & Maintenance Facilities

Functional, innovative and sustainable O&M facilities boost productivity, enhance safety and improve fleet resiliency.

Each client and each fleet has unique operations and maintenance facility needs. Identifying yours is where our work starts, and we bring a proven strategy to every step in the facility planning process — from feasibility studies and site selection to equipment analysis and stakeholder engagement. Our full-service capability leverages our specialized expertise across a range of related disciplines to deliver tailored solutions that are sustainable and widely supported.

Our experts offer a custom approach when addressing the functional needs of vehicle O&M facilities for our clients in the aviation, bus and rail transit, education, municipal and joint-use, industrial, and utilities sectors. Our facility planning teams have pioneered unique design features to improve function and the work environment. Many of these innovations have optimized work space, enhanced safety and become industry standards. From daily activities to the facility’s impact on properties surrounding it, every detail informs our analysis so we can deliver exceptional value to our clients and their communities.

The Rulebook for Vehicle O&M Facility Design

We wrote "the rulebook" as a guide for estimating site needs, construction costs and more. Inside, you will find rules for estimating bay sizes based on vehicle types. We also outline building and fire code rules relevant to specific aspects of vehicle O&M facilities. Our rulebook can even help you determine space needs for your buildings and parking. 

Prepared by our vehicle O&M facility experts, this presentation also offers rules in the form of practical advice. Rules like "make the workplace a pleasant place to work" suggest facility features for happier humans. 

Industry Firsts

The "Industry Firsts" below are samples of innovations that were first to the market and have now become industry standards. Your needs change as your organization changes; why should your design team’s approach be stagnant? Thinking outside the box is our responsibility and privilege. 

Traditional pit lighting can translate to inconsistent bright spots alternating with dark shadows. We developed a new way to light these areas using strip LED lighting in the lower level work area along posted rail. We worked with lighting vendors and designers to apply a solution not originally intended for this application, but it's a way that works better than conventional solutions to provide even light levels along the underside of rail vehicles.

When Denver Regional Transportation District's Elati O&M facility for light rail vehicles opened in 2010, it was the first to deploy a mezzanine level 18 inches above the upper work platforms. Employees can pass beneath the facility’s mezzanine with equipment such as forklifts. This design promotes the use of standard, rather than low-clearance, systems.


When both catenary poles and light poles are present in a rail yard, it can create a complex and expensive environment. We developed a solution that combines the two and is  cost-effective. By strategically locating poles that serve both purposes, and selecting appropriate light fixtures mounted at an effective height, we created a neater, more efficient yard, decreased obstructions and returned some flexibility to rail yard operations.
