The work contains a theoretical study of freight car vibrations while a group of the freight cars are under braking by retarder.The purpose is to discover possible causes of derailment.The corresponding analytical description is presented.

The solution of manta ray stencil the differential equations for the groups of carriages confirms an assumption, according to which a contact between the carriage wheel of and the rail can be lost due to the oscillations induced by braking.The results allow to present recommendation for choosing the safe regime of poison open up and say ahh t shirt braking in order to avoid the derailment.
