Summary
Two 1:9 crossings on the same track line of a double crossover are monitored, in the railway network in the Netherlands, using trains running through one crossing (Frog 1) in the trailing direction and another (Frog 2) in the facing direction. The performance of these crossings are assessed using dynamic responses measured from a Video Gauge and ESAH-M and a comparison with 1:15 crossing responses. Maintenance effects are evaluated comparing the variations of the track responses. According to the measurement results, the concentrated fatigue area in Frog 1 has a potential for plastic deformation in the wing rail, while the damage risk of Frog 2 is due to the high forces and vibration. Some advice is given to help improve track performance. This monitoring work will be continued and eventually the crossing degradation procedure will be assessed. This will provide guidance on the crossing condition estimation and will be applied in the project of structural health monitoring for a railway turnout.
