Strain data collected during the casting, curing, and detensioning of prestressed concrete sleepers manufactured by CEMEX UK in Birmingham. The data was collected for the ME01 project being carried out in the Department of Engineering at the University of Cambridge. The ME01 project is a fibre optic instrumentation and dynamic monitoring programme at Norton Bridge, UK, part of the Stafford Area Improvements Programme. The strain data was collected using fibre optic monitoring technologies based on fibre Bragg gratings.
