By using georadar on railway it is possible to obtain information about the ballast thickness and subgrade without invasive methods whilst collecting data up to 100 km/h. For this test a portion of railway between Borlänge and Sellnäs was mapped with two different georadar antennas and with different survey settings. The main purpose of this project is to establish which system gave the best data, and to ascertain what can be found in the data, and how to illustrate it along with surface point cloud data acquired from LiDAR acquisition along the track
