World first 3D GPS
sleeper laying machine

In collaboration with Laing O’Rourke, 3DX developed an automated systems to replace old wooden sleepers with new concrete sleepers. Together we scoped, designed and released the first fully automated solution using GPS (and GNSS) guidance to accurately control the sleeper lateral placement to within a 10 mm threshold.  

After completion, significant operational gains were made to remove the need to run string-lines and survey steel pegs. 3DX successfully eliminated the need for this process by increasing the productivity like nothing previously seen or experienced.
