Regular track surveys provide crucial data that allow you to identify and highlight potential issues on the condition of the railway, before becoming major problems.

It’s also used extensively for detailed design on major infrastructure projects. However, with various types of specialist track surveys available, it’s vital to understand the one that best suits your project’s needs.

Let’s understand your options when it comes to track surveys in the rail industry:

  • Geometry Measurement: Geometry measurement systems assess the alignment and profile of the tracks, ensuring they meet industry standards. This type of survey helps prevent issues related to track geometry, which can affect train stability and safety.
  • Clearance Gauging: The accurate relative measurement of structures adjacent to the track that could hit a passing train.
  • Overhead Line Survey: Ensuring through relative plane-of-rail measurements form the track to the Overhead line equipment that the pantograph of the train will may good contact with the contact wire.  
  • Platform Edge Survey: To keep stepping distance to a minimum and therefore increase the safety for passengers, platform edge surveys both ensure safe passage of the train through the platform and easy access to the train for passengers. 
  • Drainage & Utility Surveys: The detection and mapping of underground services including pipe, cables ducts and culverts using a range of survey techniques such as GPR, electro-magnetic location, manhole inspection and CCTV. 
  • Datum Plate Surveys: Undertaken to check for track movement relative to the structure on which the datum plate is fixed and recording of the design values on the plate itself. 
  • Rail monitoring: An ongoing or continuous survey of the track which is repeated at preset intervals to ensure the track or infrastructure is not being affected by adjacent works. These surveys can utilise both automatic total station measurements and/or wireless tilt sensors.

Now, you can start narrowing down your options based on your specific requirements: 

  • Assess Your Needs: Determine the primary objectives. Are you looking for routine maintenance checks, identifying hidden defects, or ensuring track alignment? Your specific needs will dictate the type of survey required. 
  • Budget Considerations: Evaluate your budget for the survey. Some surveys may be more cost-effective than others, but keep in mind that investing in more advanced technology can lead to long-term savings by identifying issues early. 
  • Timeline: Consider your timeline for the survey. Some surveys may be quicker to conduct than others. If you have urgent maintenance needs, this can be a critical factor in your decision.
