//Track measurement

HERGIE & DigiBAR

The HERGIE surveying system is an online measuring system for the adjustment and documentation of track condition It is comprised of a tachymeter-controlled track surveying trolley which optimally measures track position, superelevation, gauge and rail cant.  A lighter more portable solution was subsequently needed for a project so a digital gauge bar (DigiBAR) was developed. The bar fulfils exactly the same requirements as the trolley with the additional feature of having a wireless connection between the components of the bar and the computer. This benefit enables the user to carry and directly access the user-interface

PLASMA

PLASMA is a compact, light-weight, and highly accurate instrument based on longitudinal chord measurement. It delivers a continuous survey of rail geometry and can be used instead of heavy and expensive track control vehicles.
