Our LaserTrain (LT) is the solution to slippery railway tracks, solving a problem that has been around since the introduction of the train in the early 1800s. Falling autumn leaves, rust, oil and rubbish create a slippery layer on railway tracks decreasing the friction force between the train wheel and railway track.
The LT uses high-intensity lasers to remove the slippery top layer from the tracks. By removing this layer the level of friction can be kept in the optimal state year round.
The optimal friction level has several benefits:
- Lower energy consumption while driving the train at cruising speed.
- More power can be used for efficient acceleration and braking which increases both the punctuality as energy efficiency of trains.
- Improved safety as trains always have the same braking distance and there are no train detection problems.
- Damage normally caused by suboptimal friction levels is no longer incurred and this decreases the maintenance costs of both railway track and trains.
Our TriboMeter (TBM) provides real-time data on the friction between train and track, the so-called friction coefficient µ. Up until the TBM there was no way of measuring the slipperiness in real-time, making it hard for train conductors to adept their driving to suit the circumstances. Like driving cars on ice, a lot of energy can be wasted by applying too much power in slippery conditions. This does not only lead to lower acceleration or braking from wheel slip, but also increases the wear-and-tear significantly.
Our TBM can be attached to the train boogie and provides real-time measurements of adhesion conditions.
The TBM is certified for any type of train and with just a few vehicles equipped with TBMs, the following benefits can be achieved:
- Measuring the traction between rail and track in real-time.
- Mapping the traction of an entire rail network.
- Improving braking and acceleration schemes.
- Saving at least 1% of energy consumption.
