Subrack InterRail®

Designed for mobile use in rail transport.


  • For tough physical demands
  • Vibration-proof
  • For use e.g. in railway engineering, traffic engineering, power station engineering

Subrack InterRail®

A shock and vibration resistant subrack for use in extreme conditions

The system dimensions of the InterRail subrack are based on those of the FLEXIBLE Fi as a logical further development to produce a subrack for heavy duty use.
This allows unrestricted use of the extensive range of accessories.

The special design features of the InterRail® subrack.

  • Profile rails with a high section modulus guarantee resistance to vibrations.The refined

  • RFI-shielding concept enables high shielding effectiveness (see the RFI-SHIELDED chapter).

There are four versions of this subrack:


  1. Subrack InterRail: Shielding is not possible for the unsealed version.
  2. Subrack InterRail RFI: The RFI-shielded version.
  3. Subrack InterRail RFI - IEEE: The front is in accordance with IEEE 1101.10. The special profile rail is designed for the use of insertion and removal handles (optionally with a hot-swap function) for overcoming high insertion and removal resistance. The card guides are fitted with mechanical coding systems and special bonding for electrostatic discharge.
  4. Subrack InterRail SNCF: The special subrack with certification from the French Railways.
