The Track Recording Car EM100U, system Plasser & Theurer, is a heavy duty track recording and inspection vehicle, with two (2) trucks, each consisting of two axles. One truck has both axles driven, the other truck is a running truck. The measuring systems measure, record and analyse defects of the track, the rails, and measure the track clearance profile, at speeds of up to 110 km/h, under loaded conditions, similar to a train traveling along the track.
The video recording systems provide images of the track and its surrounding, the rails and the track components.
The rail flaw detection systems allow ultrasonic testing of the rails.
The optional ground penetrating radar provides track sub structure measurements.
Therefore, the measurements and video images fully represent the actual track and the rail of the loaded track, and the catenary wire structure under realistic dynamic conditions.
The Rail Profile Measuring System – also called Optical Rail Inspection and Analysis System – incorporates the latest laser and video camera technology to provide immediate feedback on the profile and wear condition of the rails while travelling at track speed.
The rail profile measuring system consists of the following parts:
- Two rail profile sensor heads
- One rail profile measuring computer for processing the data recorded by the sensor heads
- One electronic control unit (ECU) serving as the interface between the computer and the sensor heads as well as the power supply for the sensor heads
- One compressor for window cleaning.
The rail profile measuring system’s sensor heads are mounted on a bogies of the vehicle to view the condition of the rail under dynamic load. The measuring computer and ECU are housed inside the vehicle. To keep the optical windows from soiling, Plasser installs a compressor which blows clean air across the optical windows of the sensor heads.
