SBB uses fire trains to cool railway tracks during extreme heat, preventing track deformation and reducing the risk of accidents on Switzerland’s rail network. This is reported by the railway transport news portal Railway Supply.

When rail temperatures exceed 60°C, metal expands, which can cause misalignment and derailments. Therefore, SBB dispatches fire trains that spray water on the rails while moving.

SBB Deploys Fire Trains to Cool Down Tracks

Each fire train measures 9.5 meters in length and weighs 12.6 tons. It carries up to 28,000 liters of water, and an extra tank with 45,000 liters can be added to increase cooling capacity.

Currently, SBB operates 16 such trains to keep the rail system safe during heatwaves. In addition to cooling, they wash drainage pipes and remove dust during ballast work, making them highly versatile.

SBB Explores Solutions to Prevent Track Overheating

SBB tested alternative methods to reduce rail heating. In 2019, the operator painted tracks white, expecting to slow heat absorption, but the experiment proved ineffective, and the project was abandoned.

Using fire trains highlights the importance of proactive safety measures. With climate change and frequent heatwaves, such solutions are critical to ensuring uninterrupted railway operations.
