Bumps in High Speed Rails: What is Tolerable?

California is planning a high speed train (HST) to link Los Angeles, San Francisco, and Sacramento. Texas is planning a high speed train to link Houston to Dallas. In both cases, the embankments and bridges over which the train will travel are likely to develop bumps arising from subgrade soil movements. What is a tolerable bump for a train travelling at 400 km/hr.? That is the question. This project will advance knowledge in this area and provide guidance as to what bump is tolerable at what speed. This project is building upon previous studies of bumps at the end of railway bridges, but extends the work to much higher speeds associated with high speed trains.
