The Dutch traffic safety board (IVW) banned BAM from using Speno trains until it could prove that it could operate them in a safe manner. As this ban resulted in the tracks not being ground anymore, the ban was lifted on 4 August 2010 as long as BAM took extra precautions to run the trains safely.

The other main activity for which specially designed Speno trains are used is measuring and inspecting railway tracks. With these trains the tracks can be inspected in "real time" while the train runs over the tracks: with video, infra-red recorders, acceleration equipment and other high-tech

In 1985 it introduced the first inspection train that could find any flaws in the tracks in real time by simply having the inspection train run along the tracks at normal speeds. This allowed for inspection of the tracks without having to shut down or slow the other traffic on that route.

measuring tools the quality of the rails and points is monitored and recorded. After running over a specific route, the system generates reports containing all (potential) problems with the tracks.
