The Behaviour of the Bridges with the MW Steering Bar

The track-bridge interaction is a widely discussed and important topic today, as the modern railway bridges commonly exceed the maximum dilatation lengths allowed for the continuous welded rail. In this case, the Meyer-Wunstorf (MW) steering bar is one of the suitable solutions that can move the fixed point of the bridge to the middle of the span and thus exceed the possibility of the application of the continuous welded rail without any rail expansion devices. However, this solution is new in the Czech Republic and its functionality and durability should be verified. The paper deals with the extensive load tests made on the first Czech railway bridge with the MW steering bar. The two-track railway arch bridge on the Tábor - Sudomerice track crosses the D3 highway with the span of 100 m. The load tests were focused on the horizontal brake and acceleration forces with the heavy train (totally 1056 t) and four locomotives of weight 318.6 t. During the test, a number of values were measured, such as stresses in the rail and MW system, movements of the MW and the bridge, temperature. The behaviour of the steering bar and the bridge – track interaction is described and compared with the design and theoretical assumptions. The paper also gives the recommendations for the practical design and analysis of the MW system.
