Heavy-haul in China: Investigating durable elasticity for superstructure
Ballast is the weakest link in rail superstructure. However, by mounting Under Sleeper Pads (USPs), ballast tamping requirements can be reduced and the availability of the track can be significantly increased. Here, Getzner colleagues, Dong Huiding, Ferdinand Pospischil and Harald Loy compare elastic and non-elastic track components, with details of…
