Transforming Urban Mobility in Texas

Stadler and the Austin Transit Partnership have signed a contract for the design of 21 all-electric light rail vehicles, with options for an additional 19 trains, to support mobility infrastructure expansion in Austin, Texas. The vehicles will be deployed on the city's first light rail line to establish a high-performance, accessible transit system.

Context of the Cooperation
The development of new light rail networks involves distinct engineering challenges in vehicle design, spatial accessibility, and physical infrastructural integration. Urban areas developing new transit corridors require fleets that provide high operational flexibility and speeds while seamlessly navigating dense city environments. To address these transit demands, cooperation was established between the vehicle manufacturer Stadler and the Austin Transit Partnership (ATP). The partnership combines Stadler’s rail car manufacturing capabilities and established vehicle platforms with ATP’s transit planning infrastructure and regional development oversight in Texas.

Technical Solution and Responsibilities
The technological solution relies on Stadler’s CITYLINK platform, configured as a five-car all-electric train with a total capacity for approximately 240 passengers. Responsibilities are allocated between the partners to align manufacturing platforms with regional operational specifications:

At a system level, the vehicles feature 100 percent low-floor aisles throughout the entire train layout. This structural architecture eliminates internal step-overs within the aisles typically required above powered wheelsets, establishing a fully accessible passenger environment. The vehicles combine mainline capabilities with urban streetcar functionalities, reaching speeds of up to 65 mph outside the city center. The interior design includes dedicated Americans with Disabilities Act (ADA) compliant zones alongside flexible multi-purpose areas for bicycles, luggage, and strollers. Greg Canally, CEO of ATP, stated that the project demonstrates a commitment to design a vehicle with features never before delivered in the United States to build a light rail system that is right for Austin.

Deployment or Implementation
The implementation program initiates a collaborative vehicle design process that incorporates public feedback on elements such as vehicle color schemes, seating configurations, accessibility features, and wayfinding elements. The first phase focuses on a nearly 10-mile alignment comprising 15 stations, with the all-electric trains scheduled to run every 5 to 10 minutes throughout most of the day. Physical vehicle assembly operations will be executed at Stadler's manufacturing factory located in Salt Lake City, Utah.

Active construction of Austin’s brand-new light rail infrastructure is anticipated to begin in 2027, providing a fully expandable baseline designed to support future growth, including a planned connection to the Austin-Bergstrom International Airport. Furthermore, the project encompasses an option for a Technical Support and Spare Supply Agreement (TSSSA) to deliver long-term lifecycle support and localized fleet maintenance partnership.
