Different projects require different applications of measurement techniques. Using a single total station, two total stations overlapping or even a GNSS receiver – the GEDO CE solution supports the ideal measurement technique for each project. Therefore, the same system can be used to build slab tracks with sub millimeter accuracy, build ballast tracks with millimeter accuracy and for documentation with centimeter accuracy. The flexible setup of the GEDO CE rail measurement trolley makes it possible to convert the trolley quickly and simply on site. This results in the best possible efficiency, depending on the required accuracy and the site.

The flexible applicable GEDO CE solution enables the complete geometrical survey of the line axis. Beside the absolute rail position, the track’s cant and the track gauge are recorded. With these recordings all necessary information for a realigning is available.

As-Built Situation Survey and Track Documentation

The flexible applicable GEDO CE solution enables the complete geometrical survey of the line axis. Beside the absolute rail position, the track’s cant and the track gauge are recorded. With these recordings all necessary information for a realigning is available. In continuous measurement, every parameter is recorded in movement. As a result, long distances can be measured fast and during traffic. Using the profiler, single points can be measured to check the clearance. In this way the distances to rail signals, signs, and other objects can be measured during the recording of the rail and without generating huge amounts of data, for example by using scans.

Slab Track

High standards are set in surveying with the purpose of building a slab track. It requires much effort to adjust an already fitted rail. That is why deviations must be detected with millimeter accuracy on site and the correction values have to be made available online. GEDO CE also delivers the precision for measuring tracks for over 300km/h – all absolutely reliable. All correction values are calculated immediately and are displayed to the user on site. This method grants a productive and smooth adjustment process and an immediate quality check. Using the GEDO CE solution reduces the risk of re-adjustments and lowers overall construction costs.

Pre-Measurement for Tamping

The one thing that really matters besides measurement precision is measurement pace. Using GEDO Vorsys, you can supply the tamping machine with adjustment data nearly in real-time – thereby avoiding idle time for the tamping machine. Because the system is not bound to the track the construction process is not interrupted and the trolley can be lifted off the track at any time, if necessary. Especially at small and medium sized construction operations, the Vorsys system can fully show off its advantages.

Continuous Data Flow

The most important thing is data – whether prior to, during or after the measurement. We guarantee easy data handling without data getting lost while using GEDO CE software products. It all starts with line data coming from the designer or the contractee. The import and the consistency check are no issue using our system. Even if the data is only available as a paper layout plan – GEDO CE is well prepared so that you do not need to spend too much time at the office. In outside work, a Windows Mobile control unit is used to run the powerful and reliable software. Data evaluation and preparation can be done fast and target-aimed. All in all, this presents a well-balanced package.
