TIE GRADING

Rail Vision is one of the market leaders in the area of automated tie (sleeper) grading. We provide linescan based imaging technology for concrete tie assessment and wood tie assessment. The assessment of concrete ties evaluates tie condition based on breaks and cracks in the concrete. Wood tie assessment focusses on the detection of whether the tie is split, broken, rotten, and wheel-cut. The assessment of wood ties also considers plate cutting measurement which uses our innovative laser based technology which can make measurements with an accuracy of 0.1 mm. A significant proportion of our tie testing work is based in North America where we provide track evaluation reports based on grading guidelines set by end users.
