Step rate sander – new system

A fleet of long distance DEMU’s were fitted with a “one shot” bottle sander system and the Operator had to replace this system, due to several low adhesion related incidents, as a franchise commitment.
The technical requirements for the proposed replacement system and the timescales could not be met by any supplier other than us.
We were given a very detailed technical requirement specification and worked very closely with the train builder to deliver a system that exactly met the technical requirements.
The first complete system – with speed and brake demand dependent step rate sanding, sand level sensing and reporting and fully interfaced with the TMS – was ready for fitment in 16 weeks from placement of order.
