Ventilation criteria for ensuring a clean environment, with low carbon-dioxide concentration, are discussed. For an acceptable indoor air-quality inside the train compartment, carbon dioxide has to be kept at a low level, say 0.1% of the air. This can be achieved by increasing the fresh-air supply rate for dilution or providing a better air-distribution design.
