The work purpose is the development of suggestions on the improvement of labor conditions for passenger car conductors. In the paper there is shown information on conductor health, diseases connected with the vibration high level impact. On the basis of the experience of CC SA “TIV” for the solution of the problem specified there are introduced suggestions on changes of the standard base regulating the fulfillment of noise metering and vibration metering test. The expediency of the changes offered is also substantiated with the potential of modern instrument-ware. The absence of the necessity for the definition of vibration indices at a motion speed up to 80 km/h is shown. A possibility to obtain objective data on vibration processes in a car during measures with the 20 km/h intervals is called into question. A regularity connecting the frequencies of dominating vibration with the speed of a car motion is determined. There are given specific recommendations on the adjustment of procedures to obtain reliable information on noise and vibration perceived by passengers and service personnel. It is emphasized that maximum noise levels arise at maximum vibration levels therefore there is drawn a conclusion on the expediency of the synchronization of these tests. On the basis of the material presented in the work the following conclusions are drawn: in the resent years are not observed improvements in conductor morbidity rates connected with the impact of vibration higher levels; on the consequences of vibration impact upon passengers it is possible to judge by a health state of conductors; the introduction of the changes offered will result also in time saving and cost decrease of test fulfillment.
