ABSTRACT
The article presents results of study concerning influence of relaxation sessions on emotional and psychophysical state of locomotive crew workers in special cabin for psychoemotional relief "Vivid silence" simulating rest in nature. Relaxation sessions appeared to cause better mood, lower blood pressure, increased reactions speed, reduced number of errors. Purposeful training of the specialists in self-regulation is extremely important for preparation to work activity and for prophylactic and social measures aimed to preserve and improve health in locomotive crew workers.

The article covers results of study concerning influence of Captopril (25 mg) therapy on occupational activity of locomotive crew workers in real night travels model on training complex "EP1M locomotive operator cabin". Findings are that single use of Captopril (25 mg) in modelled railway activity enabled to increase reliability of occupational activity, that manifested in lower number of errors in locomotive operators' actions at night, and in psychophysiologic regulation of various psychic acts.

Functional reliability of engine operator and engine operator's assistant is one of the most important factors in railway safety. Ability to railway locomotive operation is determined via suitability criteria of occupationally important qualities of operator and operator's assistant, and of nervous system functional state. Lower reliability manifested in worse functional state of engine operator or in lost occupationally important qualities can be connected with various diseases of which most prevalent are cardiovascular disorders. Transitory brain circulatory disorders can cause cognitive disturbances varying in severity. When mild cognitive disorders, precise diagnosis leads to effective prevention of the diseases development and preserved occupationally important qualities in engine operators. Neuropsychologic methods for mild cognitive disorders help not only to diagnose presence and intensity of cognitive defect, but to suggest a mechanism of its development, that eventually increases efficiency of correction.

Expert and instrumental assessment covered efficiency of telemechanic system controlling train operators wakefulness in simulation of real night travel, through special simulator complex "Locomotive operator cabin". The telemechanic system controlling train operators wakefulness, if exploited correctly, provides wakefulness of the train operators at the level sufficient for the effective work. That is supported by distribution of falling asleep cases in experiments with activated or deactivated telemechanic system controlling train operators wakefulness. The study proved efficiency of telemechanic system controlling train operators wakefulness.

The article covers personality characters of locomotive crew workers of Russian Railways JSC, and specifying a block of methods for psychologic support of these workers' occupational activities. According to the results obtained, the authors presented a thorough description of characterologic, motivational personality traits characterizing a select of locomotive crew workers, and analyzed a relationship between the traits and levels of accidents in the workers' occupational activity.

The study covered influence of Melaxene on human brain functional state. Complex dynamic (12-hour) neurophysiologic study revealed that single dose of Melaxene (3 mg) influences brain functional state--reliably increases cross-correlation parameters of global spatial synchronization of cortex biopotentials in various ranges of EEG rhythms. Analysis of functional asymmetry of spatial synchronization of cortex biopotentials in various brain areas proved that Melaxene acitvates important cross-correlation links in spatial synchronization of cortex biopotentials in left and right brain hemispheres, with dominated activity of left hemisphere.
