Why the heatwave is disrupting the UK railways
WebBecause rails are made from steel, they expand as they get hotter, and can start to curve this is known as ‘buckling’. Most of the network can operate when track temperatures heat up to 46°C – roughly equivalent to air … WebApr 11, 2024 · Typical buckling shape of the railway track and support constraints: ( a) symmetrical and ( b) antisymmetrical buckling shapes. It should be noted that the buckling shape and buckled region in the actual track can be changed due to changes in track constraints or boundary conditions. WebJul 12, 2024 · Buckling The steel rail on a railway track is a very long piece of metal that can expand or contract significantly in the summer and winter. This generates forces that try to push and pull the railway out of shape. The mass of the sleepers and ballast are designed to contain these forces and prevent the track from buckling. shelly lowe harvard
