3D clearance profile in real-time

Our laser scanners measure up to 554 profiles per second without contact. By these means, objects in the track environment of only a few centimeters in size can be detected even at high travelling speeds.

Easy detection of violations of the clearance gauge

The scan data show when objects protrude into the clearance profile.

3D Clearance Profile

Free travel for trains

Shifts in the track bed or objects protruding into the track area pose a danger to rail traffic. This applies to tunnels or platforms as well as along railway lines, where vegetation can protrude into the train corridor. In order to maintain the specified clearance profile, it is measured at regular intervals by special measuring trains. For this purpose, Deutsche Bahn (DB) uses the LIMEZ clearance measuring train, equipped with cutting edge measuring technology by Fraunhofer IPM.

Clearance Profile Scanner CPS / High Speed Profiler HSP

The Clearance Profile Scanner CPS and the High Speed Profiler HSP record the position of the track bed and the clearance profile of railway tracks – in other words, the limits specified around the track that have to be free of obstacles.

The laser measurement system CPS is installed on the vehicle and operates without contact. It scans the clearance profile in a range of almost 360° perpendicular to the direction of travel and references the data to the center of the track. The laser scanner performs 200 profile measurements per second - the high-speed variant HSP even 554 in the same time. In addition to the clearance profile, the system also records objects near the track. The data is output three-dimensionally in real time and forms the basis for maintenance work.
