SPITZKE expands machine fleet

The USP 4000 SWS ballast distributing and profiling machine and the Unimat 09-4×4/4S universal tamping machine add to SPITZKE’s fleet of track maintenance machines.

At the 2017 International Exhibition for Track Technology, iaf, Ingo Wiermann, Head of Coordination of Assembly Line Projects, SPITZKE SE, was delighted to receive the new ballast distributing and profiling machine. In the summer, final calibration works were made and approval procedures were carried out by the Federal Railway Office in Plasser & Theurer’s Linz factory, before the two new machines travelled under own power from Linz to Großbeeren near Berlin. The new USP 4000 SWS is operated together with the Unimat 09-4×4/4S universal tamping machine. The machines were operated in Birkenwerder for the first time. By the end of 2017, the machines had carried out more than 50 assignments. 

We are pleased with the extension of our fleet of track maintenance machines, as modern technology is the basis for our work.


The USP 4000 SWS produces a perfect ballast bed for tracks and turnouts – in just one pass. When designing the machine, a particular focus was placed on the reduction of noise and dust. This machine is a typical example for the effective collaboration between SPITZKE group and Plasser & Theurer. Based on the customer’s desires and the technological progress achieved by Plasser & Theurer, an innovative machine concept was developed.

The USP 4000 SWS is one of the first vehicles to comply with the TSI Noise 2015 (“Technical Specification for Interoperability Relating to the Subsystem Rolling Stock – Noise”), which stipulates uniform European threshold values for new rail vehicles.

In the past, SPITZKE used SSP 110 SW ballast regulating machines. The new USP 4000 SWS runs more quietly. Thanks to the special position of the sweeper unit, it also reduces the operator’s exposure to dust. The newly designed work cabin offers optimum view onto the ploughs. Both drive cabins provide improved visibility during transfer travel. The “One pass method” makes it possible to distribute and profile ballast in one pass. The new design particularly benefits transfer travel: While the SSP 110 SW was towed at the rear of the train, the new USP can take any position in the consist. The machine operators had to get used to the modern control system and all its operating controls, but praised the powerful and modern machine.
