An adjustment device for a track conditioning unit has a measuring unit for determining a lateral offset of a rail, travelled on by a rail vehicle, relative to an effective range of a track conditioning unit or a measuring unit for determining the relative position of a bogie with respect to the rail car body. The adjustment device contains a determining unit for determining an actuation command for an actuation unit in accordance with the determined lateral offset between the effective range of the track conditioning unit and the rail. Part of the adjustment device for the track conditioning unit is also an actuation unit for actuating an actuator unit of the track-conditioning unit with an adjustment command which is generated on the basis of the actuation command. The actuator unit adjusts an effective range of the track conditioning unit on the basis of the adjustment command.

A high speed thermal imaging system includes a thermal imaging camera, the camera including a lens. The housing further includes a front portion and rear portion. The camera and lens are disposed in the housing, which further includes an opening on the front portion. The lens has a field of view through the opening. A rotating shutter disposed in the housing. The rotating shutter may be located between the opening and the optical path of the thermal sensor. The housing may be disposed near a rail track. The lens has a field of view for an object or objects of interest, such as a high speed passing train that includes bearings and brakes of railcar vehicles, (i.e. locomotives, railcars, etc.). The camera may be operable to capture thermal images of the passing rail vehicle wheels including the bearing and brake areas.
