In the railway industry, projects require different applications of measurement techniques. The Trimble Railways GEDO Trolley system offers suitable measurement techniques for each unique project. The solution provides users with a single total station, two total stations overlapping, or even a GPS/GNSS receiver, combined with powerful railways software to complete even the most complex railways projects. Therefore, the same system can be used to build slab tracks with sub-millimetre accuracy, build ballast tracks with millimetre accuracy, and for documentation with centimetre accuracy. The flexible setup of the Trimble Railways GEDO Trolley System makes it possible to convert the trolley quickly and simply on site, resulting in the best possible efficiency. The solution enables advanced process and workflow integration for complete Railway Lifecycle Management, from the feasibility phase, through design and construction, to the subsequent maintenance phase.Contact Mike Lundie, Optron Geomatics, Tel 012 683-4500, mlundie@optron.com
