Recommendation 13: Flangeway clearance requirements
From Formal Inquiry: Potters Bar derailment of 10 May 2002 — Final Report (RSSB FI2013/F), published 18 March 2005.
Recommendation
Consideration should be given to revising the requirements for setting flangeway clearances in points in order to avoid contact between the flangebacks of wheels and open switch rails over the permissible ranges of wheelset and track geometry. The revision should take into account the permissible geometry of wheelsets of vehicles operating in international traffic and the relevant implications of any emerging European Standards dealing with wheel and rail geometry.
