标题：Simplified Analytical Description of Wagon Movement with Braking Action on the Marshalling Hump Section of the First Braking Position under the Impact of Fair Wind
摘要：In article as the result there has been obtained easy by appearance analytical formula for defining wagon acceleration during braking action. It has been established that wagon acceleration on a particular hump section is dependent on all the forces (wind impact, sliding friction, medium, snow and frost impact,) acting upon the system “wagon-track” and on the mass of the wagon with cargo nonregistering wheelpair mass. On the basis of the wagon acceleration value and known time of retarder braking there has been defined a specific value of rolling speed and wagon braking path according to the hump gradient angle and wagon initial speed on the section.
