Experimental Study on Vibration Characteristics of Unit-Plate Ballastless Track Systems Laid on Long-Span Bridges Using Full-Scale Test Rigs [PDF]

open access: yesSensors, 2020
In this work, we present a series of hammering tests on full-scale unit-plate ballastless tracks used for long-span bridges. There is no denying that it is a new attempt to pave ballastless tracks on high-speed railway long-span bridges; the related ...

Railway superstructure for high-speed rails

open access: yesActa Polytechnica CTU Proceedings, 2021
The construction of the track is solved as a conventional (with track ballast) or as a ballastless track (without track ballast). When deciding on the choice of the most suitable track design for high-speed rail, it is necessary to emphasize that with ...

Dynamic response of CRTS I double-block ballastless track under three-dimensional temperature and falling-shaft impact loadings

open access: yesAdvances in Mechanical Engineering, 2021
The CRTS I double-block ballastless track under the coupling effect of temperature and falling-shaft impact is more adaptable to actual operation. However, domestic and foreign research has only focused on either temperature or train loadings.
