Description

Sanders have long been used in GB Rail, where sand is dispensed from the train to improve train traction and braking performance in low adhesion conditions. GB trains typically dispense sand ahead of the third axle, at a rate of 2kg of sand per minute per wheel and with a low speed cut-off at 10 mph. A recent comprehensive programme of track testing has determined the benefits that could be achieved by:

 

  • Variable-rate sanding (i.e. higher sand flow rates at higher speeds), and
  • Distributed sanding (i.e. multiple sanders distributed along the train).

 

The presentation will describe the testing programme and some of the issues that had to be overcome in order to realise its objectives, and then present the results and set out the braking performance benefits of the different sanding configurations, suggesting an optimum sander configuration for the future which will help to unlock network capacity improvements.

 

Presenters

Liam Purcell - Principal Consultant, Track and Wheel-Rail Interface Assurance, Ricardo Rail

Liam is a Chartered Civil Engineer with fourteen years’ experience in the railway industry; primarily as a track consultant, and with particular expertise in wheel-rail adhesion, vehicle-track interaction and derailment investigation. Recent work includes industry research projects and independent assurance of infrastructure projects. He is familiar with the installation, renewal and maintenance of railway track, and has a sound understanding of railway vehicles, including the installation of specialist systems.

 

Daniel Hamm – Lead Rolling Stock Engineer, Standards, RSSB

Dan is a Chartered Mechanical Engineer, and has worked in the rail industry since 2000 when he started a graduate training scheme in Rolling Stock Systems at London Underground (Infraco BCV). He moved to Angel Trains, where he was responsible for various cross-vehicle components, including transmissions and final drives. This led to him being seconded to the Cologne office to investigate problems on European locomotives, and so was on the European side of the business when it was separated from the UK part. He subsequently spent 7 years living and working in Antwerp for Angel Trains (later known as Alpha Trains), responsible for delivery of different projects associated with locomotive modifications and maintenance, before taking the role of Head of Heavy Maintenance, responsible for everything related to the HM works on a fleet of approximately 350 locomotives operating across Europe. In 2016 he left Belgium to return to the UK and joined RSSB as Lead Rolling Stock Engineer, responsible for train systems in the Standards dept, where he supports the development and management of British, European and International standards (including TSIs), as well as providing technical input into R&D projects.
