How brittle can a railway curve track be
Nov 15, 2023| on my country’s railway lines
Curved tracks occupy a large proportion
its geometry
Directly controls train speed and affects operational safety
on a straight road
The track is relatively evenly stressed
But it will be much more complicated on curved sections.
It is easy to cause rail diseases
therefore
Curves are one of the three weakest links in railway lines
With the gradual expansion of the railway network, mountainous sections have been greatly increased, forming many curved lines.
When the train runs downhill for a long time, it needs to brake for a long time to control the speed. At this time, huge heat will be generated, which will greatly test the rail material and provide conditions for the generation and expansion of cracks, which will eventually evolve. Peel off the pieces.
As the peeling off disease continues to worsen,
Not only will it affect the ride comfort
And it will have strong impact on wheels, ballast, sleepers, etc.
Seriously affects the stability of the wheel-rail system
It is easy to induce other hidden dangers
It may even affect driving safety
Leading to accidents such as derailments and vehicle jumps
