Services - Track Control (TCM) Survey

Track Control Mark (TCM) Surveys are generally undertaken to provide permanent TCM plaques to assist with track maintenance.

Different TCM types exist depending on the rail network being worked in.  Stainless steel pins (SSP’s), Brass Bars, Galvanised Steel Pipe (GIP’s) all form TCM’s in different areas.  Plaques are sourced, engraved and affixed as part of the process.
