The use of train lavatories by the passengers during their journey was investigated. Selective samples in Petri dishes were exposed for 1 or 2 minutes at different times against the direction of train motion. The analysis showed that enterobacteria (E. coli, Klebsiella, coliform bacteria, Proteus) and chromogenic bacteria (Pseudomonas, Achromobacter, Pseudomonas aeruginosa) can be verified in addition to yeast fungi, mould, actinomyces and micrococci. The colony count obtained depends on the climatic conditions, the passenger frequency as well as the site and period of exposure. The "air tunnel" formed by the travelling trains must be looked upon as contaminated. I would be advisable for the trains to travel with the windows locked. The intestinal bacteria are little risk to the environment but definitely injurious to the passengers themselves.
对乘客在旅途中使用火车厕所的情况进行了调查。在培养皿中的选择性样本在不同时间迎着火车行驶方向暴露1或2分钟。分析表明，除了酵母真菌、霉菌、放线菌和微球菌外，还能检测到肠杆菌（大肠杆菌、克雷伯氏菌、大肠菌群、变形杆菌）和产色细菌（假单胞菌、无色杆菌、铜绿假单胞菌）。所获得的菌落数取决于气候条件、乘客流量以及暴露的地点和时间段。行驶中的火车形成的“空气隧道”必须被视为已被污染。建议火车行驶时锁好窗户。肠道细菌对环境危害较小，但对乘客自身肯定有害。
