Analysis of Traffic Accidents and Development of Means to Improve Railway Transport Safety

Akhtyamov, Rasul / Titova, Tamila

The article provides an analysis of violations in train and shunting operations, which can lead to emergency situations with transported hazardous materials. Analysis of statistical data on accidents in railway transport showed that when transporting hazardous materials of various classes, the main reason for the release of a hazardous substance into the environment is mechanical damage to the integrity of a railway tank as a result of a train derailment. To improve railway transport safety, a system to improve the reliability of monitoring the derailing of a rolling stock car has been developed. At the same time, continuous monitoring of the position and timely detection of the rolling stock cars’ derailment from the track during movement is carried out. On the basis of the calculations, it was found that when creating an additional load on the axle of the car wheelset in the form of a device for monitoring the rolling stock car derailing from the rail fixed on the side frame of the bogie, the stresses in the sections under consideration do not exceed the normative permissible values. The use of the proposed device makes it possible to fully automate the process of monitoring the rolling stock car derailing and provides the possibility of continuous monitoring of the car wheel pair state on the track.
