[Physical factors of the industrial environment and traffic safety].

The paper deals with the problem of optimization of working conditions of engine drivers in the control cabs of up-to-date locomotives, by toughening the sanitary-and-hygienic requirements for the levels of bad industrial factors. The authors associate the optimization of working conditions with the necessity of strengthening the reliability of their driving activity due to the increasing rail movement speeds and the transfer to one-person rolling-stock operation, and other factors.
