Train HVAC Market Growth Drivers: What’s Behind The Acceleration?
The increasing demand for public transport is expected to boost the growth of the train HVAC market going forward. The purpose of a heating, ventilation and air conditioning (HVAC) system is to offer thermal comfort and contribute to the maintenance of good indoor air quality (IAQ). Rapid development in the rail industry and a great deal of investment in the sector are enabling people to opt for public transport, especially trains. Due to this demand, trains are becoming crowded, and there is a huge need for HVAC systems to maintain a good quality of air. For instance, in January 2025, according to the UK Department for Transport (DfT), a UK-based government agency, Great Britain recorded 1,612 million rail passenger journeys in the financial year 2023-2024, up from 1,385 million in 2022-2023, a 16.4% increase. Therefore, an increase in the demand for public transport drives the train HVAC market.

Train HVAC Market Trends: What’s Defining The Industry’s Next Phase?
Major companies operating in the train HVAC market are developing innovative products, such as propane-based HVAC systems, to offer energy efficiency. A propane-based HVAC system is a heating, ventilation, and air conditioning system that uses propane as its primary fuel source to provide heating and cooling for residential or commercial spaces. For instance, in July 2024, Liebherr-Transportation Systems (Liebherr TS), an Austria-based company that develops, designs, tests, and supplies systems and components for the transportation industry, launched the propane-based train HVAC systems for Stadler. The use of propane in alternative HVAC systems highlights the rail industry’s commitment to sustainability, as companies aim to lower emissions not only from train engines but also from all components of the vehicles. This innovative approach demonstrates a holistic effort to enhance environmental performance across the entire rail operation.
