# Commission Regulation (EU) No 1299/2014 of 18 November 2014 on the technical specifications for interoperability relating to the ‘infrastructure’ subsystem of the rail system in the European Union (Text with EEA relevance) (revoked), Appendix J: Safety assurance over fixed obtuse crossings

Extent: E+W+S+N.I.
Status: repealed

(J.1)
The fixed obtuse crossings should be designed in order not to have a too long unguided length. In obtuse crossing check rails cannot be constructed to assure guidance over the whole length. This unguided length can be accepted up to a certain limit, defined by a reference situation defining:

The following graphs allow simple verification of unguided length for specific situation with different crossing angles, height of check rail and different crossing curvature.
