Loram offers a range of GPR solutions, from our complete data collection and analysis services to deployable GPR systems available for rail car mounting.

Loram’s standard hi-rail based survey system uses three 400 MHz antennas that are specially designed for the high-speed, non-invasive measurement of ballast and track formation. The antennas are deployed at the track centerline and at both ends of the ties.

In addition to the hi-rail based method of GPR data collection, Loram offers an on-board solution, where its GPR surveying equipment is installed onto one of the railroad’s geometry cars to survey the track as the car travels.

Both the hi-rail based and on-board based systems work in electrified track territory and in urban environments hindered by background electromagnetic noise.
