These Regulations amend the Railways and Other Guided Transport Systems (Safety) Regulations 2006 (“the 2006 Regulations”) (S.I. 2006/599) in order to implement Commission Directive 2014/88/EU amending Directive 2004/49/EC of the European Parliament and of the Council as regards common safety indicators and common methods of calculating accident costs (O.J. No. L201 of 10.7.2014, p.9) (“the 2014 Directive”). Directive 2004/49/EC of the European Parliament and of the Council on safety on the Community’s railways (O.J. No. L164, 30.4.2004, p44) sets out (in Annex I to that Directive) a number of common safety indicators (“CSIs”) which are harmonised measures used by all Member States to provide an overview of safety performance and monitor the development of safety in different Member States. Transport operators who carry out operations on the mainline railway are required to report on statistics for these safety indicators under regulation 20 of the 2006 Regulations.
