The WSM 08-275 3SY can be used to tamp high-speed switches and switches with tight radii.
Even tracks and switches on Y-sleepers are no problem for this high-performance switch tamping-aligning machine.

WSM 08-275 3SY

Weighty in performance

The expansion of the railway infrastructure goes hand-in-hand with a steady increase in the number of intersections with installed switches. Increasingly heavy elements need to be installed to ensure that these points on the railway networks can withstand the high loads exerted by freight and passenger traffic.

The linear meter weight on high-speed lines or those with tight radii is particularly large, which means that optimal tamping below switches is essential – a task that the high-performance tamping-alignment machine WSM 08-275 3SY masters to perfection. This also applies e for small radii, as the high loads are absorbed by the stability of the switches.

Tamping the subgrade below switches is a one of the special challenges in track construction work due to the split track structure; however, thanks to the WSM 08-275 3SY we are able to deliver absolute quality in this field.

The Group has two special machines, both of which with 3-rail lift systems, that allow us to lift and tamp below any kind of sleeper, even Y-sleepers. In combination with various other systems and equipment used for measuring and individual adjustment excellent tamping results can be achieved.
