Open Mathematics - for iPod/iPhone

The Severn Valley Railway is one of Britain's best known steam railways. Over much of its length, there is only a single track, with passing points at various points along the line. As with any commercial rail operation, the timetable needs to meet passenger needs and health and safety requirements. The five video tracks in this album follow the work of railway employees as they monitor and develop the service to suit passenger demand and ensure safety systems are in place. The material forms part of the course MU120 Open Mathematics.
