Mechanical and vibrational testing of clamped rail steel assembly

The mechanical clamps used for temporarily clamping broken rails before replacement or thermit welding must be reliable as any loosening may lead to rail misalignment and the consequences will be dire. In this paper, a setup with 2 broken rails and 4 clamps were replicated in the laboratory to perfo...
