Train HVAC Market Report 2025

The train HVAC market size has grown steadily in recent years. It will grow from $14.17 billion in 2024 to $14.75 billion in 2025 at a compound annual growth rate (CAGR) of 4.1%. The growth in the historic period can be attributed to increasing railway infrastructure development, growing passenger rail travel, focus on energy efficiency, enhanced passenger experience, regulatory standards and compliance.

The train HVAC market size is expected to see strong growth in the next few years. It will grow to $18.09 billion in 2029 at a compound annual growth rate (CAGR) of 5.2%. The growth in the forecast period can be attributed to high-speed rail expansion, focus on sustainability, increasing urbanization and commuting, integration of smart HVAC solutions, upgrading existing rail fleets. Major trends in the forecast period include noise reduction in HVAC systems, use of variable refrigerant flow (VRF) technology, adoption of all-electric HVAC systems, customization of HVAC systems for different train types, global standardization in train HVAC components.

The expected growth of the train HVAC market is attributed to the rising demand for public transportation. Increased investments and development in the rail sector have led to a surge in train usage, resulting in crowded conditions. The need for efficient heating, ventilation, and air conditioning (HVAC) systems to maintain air quality in trains is evident from the Office of Rail and Road's data from December 2022, reflecting a significant increase in rail passenger trips.

The anticipated growth in the train HVAC market is closely linked to the increasing development of railway infrastructure worldwide. This development, encompassing the planning, enhancement, and construction of railway systems, necessitates advanced HVAC systems to ensure passenger comfort. Notably, The White House announced in December 2023 a substantial allocation of $8.2 billion to support significant passenger rail projects across the United States, emphasizing the crucial role of railway infrastructure development in propelling the train HVAC market.

Strategic partnerships have emerged as a significant trend gaining traction in the train HVAC market. Major companies in this sector are collaborating to drive market development. For example, in October 2024, Winsupply, a U.S.-based distributor of plumbing, heating, cooling, and industrial pipe, valves, and fittings, partnered with Trane Technologies, an Ireland-based company specializing in train HVAC solutions. This partnership provides Winsupply local companies with enhanced opportunities for growth and success in the HVAC sector. It allows local businesses to access the necessary resources and support to effectively implement new HVAC technologies.

Major companies in the train HVAC market are focusing on developing innovative products, such as propane-based HVAC systems, to enhance energy efficiency. A propane-based HVAC system utilizes propane as its primary fuel source to provide heating and cooling for residential or commercial spaces. For example, in July 2024, Liebherr-Transportation Systems (Liebherr TS), an Austria-based company that designs, develops, tests, and supplies systems and components for the transportation industry, launched propane-based train HVAC systems for Stadler. The incorporation of propane in alternative HVAC systems underscores the rail industry's commitment to sustainability, as companies seek to reduce emissions not only from train engines but also from all vehicle components. This innovative approach reflects a comprehensive effort to improve environmental performance across the entire rail operation.

In November 2022, Trane Technologies, a US-based company operating in train HVAC systems acquired AL-KO Air Technology for an undisclosed amount. With this acquisition, Trane technologies company expands its platform of HVAC for railways and both companies would continue to help their customers achieve their goals for high-performance heating, cooling and ventilation, and indoor air quality. AL-KO Air Technology is a Germany-based company operating in train HVAC.

Train HVAC, encompassing heating, ventilation, and air conditioning systems, regulates air movement between indoor and outdoor spaces, controlling temperatures in both residential and commercial train structures while purifying the air.

Train HVAC systems primarily serve two main train categories: passenger and freight. Passenger transport involves the collective count of travelers utilizing inland transportation within a specified network. These systems comprise vapor-cycle and air-cycle mechanisms, incorporating critical components such as air dampers, blowers, compressors, condensers, inverters, evaporators, among others. Refrigerants utilized in these systems encompass conventional options as well as natural refrigerants, notably carbon dioxide (CO2).
