A field study was conducted to determine the vibration characteristics of subway train cars in terms of the whole-body vibration exposure levels transmitted to train operators. A total of five car types was tested and analyzed. To be able to compare different car types, vibration measurements were made under conditions for which all variables other than the car type were constant. The study was carried out in accordance with the measurement and evaluation techniques outlined in the ISO 2631 (1985) standard on whole-body vibration. The results obtained were analyzed to assess the effectiveness of each car type in reducing the mechanical vibrations transmitted to train operators. Up to 31 % lower overall vibration levels were observed for cars with air-cushioned suspensions than for the cars with spring-based suspensions. Operators of trucks, buses, trains, helicopters, fork-lifts, and forestry, mining, and agricultural equipment are exposed to occupational vibration. Daily exposure to whole-body vibration over many years may cause psychological and physiological disturbances. Studies that investigate the sources of vibration and factors that influence vibration exposure levels, and that compare different equipment to provide options to industry, may contribute to the improvement of health, safety, and well-being of the operators.
