Having leaves on the track might not seem damaging to you,
but a train operator will have a totally different view. If there is foliage on
tracks it leads to making it harder for the train to stop and also messes with
the anti-collision signals. However, such greenery might not be a problem for
much longer. Dutch railways are currently testing a new way of cleaning tracks.
Using a laser system, they zap the leaves and other such material to stop it
from reaching the wheels. For this purpose, sand gels and water jets are
already being used, but they are limited in supplies and also damage the rails.
With the trains use lasers, it will actually dry the metal while cleaning and
prevent leaves from sticking to it.
This new Laser system can only work at a speed of 50MPH
which means High speed trains won’t be able to clean the track in their course.
However, this limited use of the laser system is also quite beneficial. It will
make the track safe which is good for passenger’s safety and will also help
reduce delays that occur due to cleaning of tracks.
