T1205 Relationship between train horn test measurements and perceived sound levels on the track

Tender description

Building upon documented requirements and previous studies, this project sets out to ascertain the distance(s) at which train horns installed and set within Technical Specifications for Interoperability (TSI) and Notified National Technical Rules (NTR) limits can be effectively heard by track workers, considering the anticipated range of environmental and topographical parameters. Audible warning devices (horns) are fitted to trains so that these can be utilised in a number of situations, including: • To warn people that a train is about to move (in sidings, etc) • When approaching anyone on or near the line • As a train enters and leaves a tunnel • When approaching some public foot crossings where there is no other form of warning available. A pre-tender suppliers meeting has been arranged for 28 February 2020 at 10:00 - 11:30, at RSSB's offices in Moorgate, London. (The Helicon, 1 South Place, London, EC2M 2RB) The purpose of this meeting is to: • Provide an outline of the project proposal • Provide interested suppliers an opportunity to discuss, understand and inform the research specification. Suppliers wishing to attend in person or by dialling into the meeting should contact Tanja.Odinsen@rssb.co.uk to confirm attendance by 26 February 15:00.
