• Fully automated and manual monitoring systems
• Non-contact surveying and remote monitoring

Technologies
Greenrail Solutions Ltd feel that equipping ourselves with the latest and most accurate technologies available not only makes the deliverable to our clients reliable but makes the collection of the data more efficient.

This often reduces the time required to obtain the relevant information compared to more traditional methods reducing costs to our clients.

Please see below information on the technical equipment that we have invested in, if you would like any further information on workflows please contact us.

Leica TPS1200+ These robotic total stations are an integral part to all our Survey and Engineering works from controlling and maintaining our traverse networks to positioning the Amerg Trollies.

Leica GNSS1200+ GPS/GNSS systems are being used more and more in the Rail Industry as an accurate tool for establishing and checking long, linear traverses.

Leica DNA03 The most accurate digital level available from Leica Geosystems is used by our Surveyors to establish datum marks throughout the working corridor. They are also used to control the level of our traverse networks.

Leica HDS6000 The Leica HDS6000 is the industry's most popular phase-based scanner allowing our surveyors the advantage of ultra high-speed, phase-based laser scanning. The HDS600 can scan up to 508,000 points per second and work in bright conditions or complete darkness enabling the HDS600 to scan objects in tunnels or at night that could easily be invisible to the human eye.

Amberg GRP1000 The Amberg GRP1000 rail trolley combined with the Leica TPS1200+ total station enables us to gain millimetre geometry of the track giving us all Chainage, Gauge, Super Elevation and 3D Track Co-ordinate information in real-time. More traditional track survey methods require the information collected to be post-processed adding cost and more importantly time to the project.

Amberg GRP5000 The Amberg GRP5000 rail Trolley is a combination of the above GRP1000 and the Leica HDS6000 Laser scanner. In addition to measuring track geometry this trolley profiles tunnels, structures and OHLE for ''Clearance Surveys''.
