Measuring Rail Gauge Using Laser Scanners

Older | Newer

In order to keep commerce moving, railroad companies as well as shippers, rely on inspections and preventative maintenance to keep trains moving safely. Train rails are regularly inspected for defects and one of the criteria for train rail inspections is rail gauge. In the United States, the standard rail gauge is 56.5 inches and it is important that rails do not get closer than 56 inches or further than 58 inches.railway measurement using laser


Rail gauge is measured 5/8 of an inch under the top of the ball of the rail. For many years, manual measurement tools have been used and trusted but this process can take much longer. Fast and highly accurate inspections can be done with the use of a pair of AP820 scanners. Engineers can inspect miles of rail gauge without even leaving their inspection vehicle. This is a highly valuable tool that can allow for more frequent and precise measurement of rail gauge to ensure the safety of trains.
