Question 1

What is loaded track geometry measurement?

Accepted Answer

Loaded track geometry measurement means that the geometric position of the track is measured under load, using a heavy measurement wagon that simulates real traffic conditions. This provides a more realistic picture of the track condition compared to unloaded measurement.

Question 2

Which standards does the Eco Rail measurement rig follow?

Accepted Answer

Our measurement rig performs measurements according to European standards EN13848-2 (measurement systems) and EN13848-3 (evaluation of track quality). These standards ensure that measurement results are reliable, repeatable and comparable.

Question 3

When is a railway track inspection needed?

Accepted Answer

Track inspection and measurement are required regularly according to regulations, during new construction and after maintenance work, when track defects are suspected, or after derailments. Regular track measurement is an essential part of preventive maintenance.

Question 4

What does a track measurement wagon measure?

Accepted Answer

A measurement wagon measures track gauge, cant, twist, alignment and vertical profile. These parameters provide a complete picture of the track's geometric quality and any deviations.

Question 5

Can Eco Rail perform track measurement across Sweden?

Accepted Answer

Yes, our measurement rig is available for assignments throughout Sweden and internationally. Contact Lennart Jakobsson to discuss availability and planning of your measurement project.

Question 6

Can the measurement wagon also perform video documentation?

Accepted Answer

Yes, in addition to track geometry measurement, the wagon can perform various types of video recordings for documentation and visual inspection of the track infrastructure, such as rail surface condition and sleeper condition.

Question 7

What is the difference between loaded and unloaded track measurement?

Accepted Answer

In loaded track measurement, the track is measured under the weight of a measurement wagon, showing how the track behaves under real traffic conditions. Unloaded measurement shows the track condition without load. Loaded measurement usually provides a more accurate picture, especially on tracks with poor ballast or subgrade.
