International Standards and Conformity Assessment for all electrical, electronic and related technologies




The enlargement of the EU in May 2004 has made the railway sector one of the most important Public Transportation systems in the world in terms of expansion size.

CENELEC/TC 9X is responsible for the development of European Standards for electro technical applications related to the Rail Transport Industry of the European Union.


The industry comprises:

  • Rail users
  • Public and private rail transport operators (passenger and freight)
  • Infrastructure owners
  • Manufacturers and maintainers
  • Service providers (e.g. consultants, financers, etc.)
  • Public authorities (National and European)
  • Leasing companies
  • Regulatory bodies
  • Trade associations


There are over 50 major manufacturers, infrastructure owners, and operators in the sector and actively working with CENELEC. The industry provides employment to over 150.000 people.


The EU aims to achieve free and unrestricted transfer of goods, services and passengers across national frontiers within Europe. To help achieve this, the EU has adopted two Directives concerning the Interoperability of the European Railway System and the Railway Safety. The implementation of these directives is aided by standards developed by CEN, CENELEC and ETSI.
