Original Abstract

With respect to the possibility of crash accidents of trains due to delayed stopping in dead track, tracks are provided with buffer stops. Nowadays the majority of buffer stops is designed according to CD Z 9 code (České dráhy, 2002). Accidents in recent years indicate that those buffer stops are not in conformance with up-to date railway service with respect to transport safety. Means to improve the security of buffer stops use are investigated. In orders to assess the resistance properties of code-conforming buffer stops, there have been performed analyses considering train of wagons crashing with specified velocity into buffer stop. The range of buffer capabilities during the impact has been investigated. Analyses have been performed using ANSYS and LS-Dyna program packages..
