Analysis of Large-slope Metro Turnout Rail Creeping under Cycling Loads Action
Chengshi guidao jiaotong yanjiuObjective When turnouts are laid on slope, the longitudinal force increase on the track due to the cyclic braking of trains will cause uneven rail creeping phenomena， resulting in a more complex stress and deformation pattern for the turnout, and even ...

Railway superstructure for high-speed rails
Acta 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 increasing line speed, the requirements for the quality of the track geometry increase, including the ...
