- Development of the Car Body Mounted Track Measuring Device with the Inertial Mid-chord Offset Method
Abstract
A prototype track measuring device was developed adopting the inertial mid-chord offset method, which can be mounted on commercial railway vehicles. The device was installed on a track inspection car which was then tested to evaluate its practical measuring accuracy and durability over the long term. Initial results showed that the accuracy of the device was lower when used at low speed. A method was therefore sought to compensate accuracy at low speed. This paper describes the outline of the developed car body mounted device, the results of running tests on commercial lines and the compensation method used to raise track measuring accuracy even at low speed.
