DYNAMIC BEHAVIOUR OF THE SLEEPER LENGTH TRANSITION IN RAILWAY TURNOUTS

Publikation: Beitrag in Buch/Bericht/KonferenzbandBeitrag in einem Konferenzband

Abstract

Railway turnouts are important components of a railroad network. Compared to a normal
track, they are more expensive and have many areas with complex dynamics. One of these
areas is the transition from long sleepers to short sleepers at the end of a turnout. The dynamics that arise there affect both the vehicles and the infrastructure. As such, understanding
and addressing these dynamics is crucial, as they can lead to increased maintenance needs,
a reduced availability and, consequently, higher costs. To better understand the occurring
dynamics at this jump in stiffness, the actual reaction of the transition must be recorded. As
part of the FFG-Comet project Rail4Future, measurements were performed on a turnout in an
Austrian main line to this end. These measurements included recording the vertical sleeper
displacements at multiple positions in the transition zone as well as the dynamic axle loads
outside of the influenced area. The data was used to study the behaviour of this transition
zone, especially looking at influencing factors on track panel twist, such as vehicle type, axle
load and travelling speed. These new insights into the transition in sleeper length can be
used, among others, in the evaluation of vehicle-based measurements, as the measurement
itself is influenced by the vehicle.
