Karthick Subramani: PRESTRESSED-FIBRE CONCRETE SLEEPER
The figure shows the static behaviours of tested railway concrete sleepers at failures. It is clear that the tested concrete sleeper fails under sagging moment. Major shear diagonal cracks can be noticed as well as the crushing of concrete at top fibre, describing the shear-bending failure.
Concrete sleeper - Wikipedia
Concrete sleepers lack the elasticity of wooden sleepers and, therefore, ballast tracks with concrete sleepers usually have a much quicker degradation of the ballast when loaded. This is especially true in curves, turnouts and switches.
