More Elasticity for the Heavy Haul Malmbanan Line
A Convincing Argument: Under Sleeper Pads under Extreme Conditions between Gällivare and Koskullskulle
Particularly in heavy haul, ballasted track often reaches its limits. High axle loads and freight tonnage directly place a disproportionately high strain on the track. For this reason the Swedish operator Trafikverket opted to install under sleeper pads in 2014.
The challenge
- Axle load of 30 t
- High frequency, high tonnage
- Heavy haul trains with up to 68 wagons
- Weighing roughly 8,500 metric tons
- Above-average amounts of wear on high-grade rail steels and sleepers
The Getzner solution
Trafikverket knew that under sleeper pads help significantly to protect the ballast. But no-one had ever tested whether this solution would work as efficiently and on this scale north of the arctic circle before. The ideal load distribution within the track was required. This was the goal behind the attempt to reduce the stress between ballast and sleeper by enlarging the area of contact between the sleeper and the ballast. Under sleeper pads, such as those offered by Getzner, are perfect for such a scenario.


Advantages for the customer
- Effective protection of the ballasted track
- Thus, increased availability and profitability
- Less maintenance work required
- Significantly lower life cycle costs
- Improved track bed quality
- Reduction of short-pitch/rail corrugation on rails in tight curves
- Reduction of vibration emissions
- Prevention of voids under the sleepers
At Getzner, the message came through loud and clear: we needed to combine both resilient and plastic properties in our under sleeper pads.
