This article is based on an official press release from Alstom.
Alstom has announced a major agreement to overhaul the automated people mover (APM) system at George Bush Intercontinental Airport (IAH) in Houston, Texas. According to an official company press release, the €380 million ($437 million) contract includes comprehensive upgrades to the airport’s Skyway system and a 15-year extension for operations and maintenance services.
The modernization effort comes as the Houston airport undergoes a multi-billion-dollar expansion to handle surging traveler volumes, which exceeded 48 million passengers last year. We note that this infrastructure investment aims to minimize service disruptions and improve passenger flow between terminals during peak demand.
Comprehensive Skyway Modernization
Fleet and Infrastructure Upgrades
Under the terms of the agreement, Alstom will deliver 16 new Innovia APM R vehicles to replace the aging fleet. The company stated in its release that the project also involves constructing a new Operations Control Center and upgrading the system’s communications and automatic train control technologies to the Urbalis platform.
Additionally, station doors across all terminals will be replaced to facilitate safer and faster boarding. To minimize the impact on travelers while the Skyway is out of service for these upgrades, interim busing will be provided, according to the announcement.
Long-Term Operations and Maintenance
Building on a Two-Decade Partnership
Beyond the hardware and software improvements, the contract secures Alstom’s role in operating and maintaining the Skyway for another 15 years. The manufacturer noted that a dedicated 48-person on-site team will manage the system’s daily reliability.
Alstom has managed the Skyway APM for two decades using the original Innovia APM 100 vehicles. The company highlighted its strong operational track record at the airport, reporting a 99.63% availability rate for the current system in 2024.
“Modernizing Houston’s Skyway system is essential to meeting the needs of one of the fastest-growing airports in the United States. This next-generation APM will deliver more reliable, seamless travel for millions of passengers every year.”
Industry Context and Broader U.S. Presence
Expanding Automated Transit Solutions
The Houston contract builds upon Alstom’s extensive footprint in the automated transit market. According to the press release, the company’s Innovia APM systems are currently utilized at 15 different airports across the United States. Globally, the manufacturer has delivered over 30 automated people mover systems.
Furthermore, the integration of the Urbalis automatic train control system at IAH reflects a wider deployment of this technology. The company noted that its Urbalis signaling system is active on more than 190 metro lines across 32 countries, with 74 of those lines operating on a completely automatic, driverless basis. As a major supplier in the U.S. market, Alstom reports having delivered over 12,000 new or renovated vehicles for various domestic rail agencies and airports.
AirPro News analysis
We view this contract as a significant reinforcement of Alstom’s footprint in the United States transit and aviation sectors. By securing both the capital upgrade and a 15-year maintenance agreement, the company ensures a steady, long-term revenue stream while locking in its proprietary technology at a major international hub. The transition to the new Innovia APM R vehicles and the Urbalis signaling system aligns with broader industry trends toward fully automated, high-capacity airport transit solutions capable of handling record-breaking passenger growth.
