TCVT Rail infrastructure machines

As of 1 February 2002, rail infrastructure machines have to be inspected by inspection bodies. CERTIFER HHC/DRS has been accredited for performing these types of inspections (known under number I141) by the Dutch Accreditation Council, and has entered into an agreement regarding this matter with TCVT, the Dutch body for supervision on the certification of vertical transport.

Rail infrastructure machines operating on decommissioned tracks are special self-propelled vehicles capable of running on these tracks and intended for laying new tracks, replacing tracks, or performing track maintenance.

Some examples of rail infrastructure machines include:

  • Rail-based maintenance machines as outlined in EN14033-1/ -2/ -3.
  • Road-rail machines, with or without cranes or elevated worker platforms, as outlined in EN15746-1 /-2
  • Trailers as outlined in EN15954-1 /-2.
  • Demountable machines as outlined in EN 15955-1 /-2.

Thanks to many years of experience and relationships with all rail infrastructure machine manufacturers, CERTIFER HHC/DRS is able to perform these inspections with ease, and answer any specific questions you may have about deploying these machines in a professional manner.
