Transport is an important player in the economy. Many European companies are world leaders in infrastructure, logistics and manufacturing of transport equipment and traffic management systems.

This reflects in the standardization activities, which cover classical transport modes (e.g. rail, road, maritime) and horizontal issues, such as interoperability, intermodal transport, intelligent transport systems and transport of dangerous goods.
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, financiers, 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 both 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.

Sector Forum

A sector forum is a platform aiming at facilitating the exchange of information between the different stakeholders, coordinating and identifying the standardization needs in a specific field of the ESOs work.
In the railways' field there is a CEN/CENELEC/ETSI Sector Forum Rail.

European legislation and mandates

European standards are developed in the context of European legislation and sometimes come in direct support to particular Directives or Regulations.
