# The Railways (Interoperability) (High-Speed) Regulations 2002, Paragraph 1.5: General requirements


Technical compatibility
The technical characteristics of the infrastructures and fixed installations must be compatible with each other and with those of the trains to be used on the trans-European high-speed rail system.
If adherence to these characteristics proves difficult on certain sections of the network, temporary solutions, which ensure compatibility in the future, may be implemented.
