The gradual improvement of modern rail networks and the emergence of high-speed lines requires the most accurate and efficient surveying and monitoring using equipment from Leica Geosystems.

In early November 2003, the first fully
automated GradeStar-TPS 3D Dozer control
system in Europe was installed at the
Hydrex site in West Drayton, UK. The
GradeStar machine control system, based
on the robotic TPS1100 Total Stations
series, was installed on a Komatsu D41 P-
6 dozer together with Leica Geosystems
ProControl (the core 1D/2D/3D hydraulic
control system). This 3D machine control
system enables dozer operators to complete
grading work in a shorter amount of
time, more efficiently and with greater
accuracy. mer info

(Reporter 49, Dec 2004) The use of innovative 3D laser scanning technology from Leica Geosystems meant that Australian surveying company North Surveys were able to complete the survey of a section of rail network in record time and with an extremely high level of accuracy. mer info

“Without the Cyrax system enabling us to extract data under controlled office conditions we would not have been able to provide results to the timetable required. Also, collecting and labeling data in the field on a discrete point basis is very prone to error and increases time spent in a dangerous environment. Errors in discrete points are difficult to trap and will inevitably mean a revisit to site. With the Cyrax system all data could be fully QA’d by over sampling without time penalties and all processing was done off-site.”

By the end of 2002, the 219km (136 miles) long train tracks designed for speeds of up to 300 km/h (186 mph) will be completed, thereby drastically reducing travel time between Cologne and Frankfurt, Germany. mer info

There is some hard work going on in Vancouver, the Canadian Pacific metropolis. Two LEICA TCA2003 total stations with automatic target seeking operate up to twenty hours daily along the route of a new stretch of
SkyTrain track. “The beauty of the Leica Geosystems automatic target recognition instrument is that we can also work nights“, says Don Murray. mer info

A Leica TCA 1800 automatic target recognizing precision total station, controlled by the Leica APS Win Software, was in use when a bridge was moved by 23 metres below the Inter City Express main rail axis Mannheim-Frankfurt. This work on the Mannheim- Blumenau railway line was carried out by the Mannheim office of Bilfinger + Berger Bauaktiengesellschaft.
The surveyor responsible for the measured control of the undertaking H. P. Echsle, describes this operation for our readers. mer info
