Sanders

Lot 1 – Designing, planning, managing and analysing results from braking tests aimed to determine the improvement in braking performance, in simulated low adhesion conditions, that can be achieved with a single sander that varies its delivery rate with speed compared to a single fixed rate sander, and also with the benefit of distributed sanders. Lot 2 – Designing, planning, managing and analysing results from train detection tests on a number of different track circuits to determine the upper limit of sand den...
