Explained in plain English
Why do train air-cons leak?
Train air conditioning systems work by cooling and dehumidifying the air. When the system malfunctions, often due to a blockage or drainage issue, the condensed water can build up and leak into the carriage. This is what likely happened on the East Midlands Railway train, turning a journey into an unexpected indoor 'rain shower' for passengers.
