Tender description

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 density (in terms of g/m) that leads to a wheelset becoming isolated from the rail — resulting in a loss of track circuit detection — and determine how many wheelsets are required to disperse sand laid at this rate before sand can be re-applied.

For this lot RSSB will source trains and test track for the testing.
