Turnout tamping made easier

The new continuous-action machine for all line categories

One million tamping insertions – the successful Unimat 4x4 series

A series of new Unimat 09-4x4/4S turnout tamping machines will leave our factory this year. It continues the success achieved in Germany and Great Britain.

The first two machines due in 2016 were delivered in April. One month later, they were already put into operation. A Unimat 09-4x4/4S was delivered to Gleisbau-Busching-Wagner GmbH in Germany. The other machine was acquired by the Polish company Torpol. Fitted with and integrated dynamic track stabiliser, it belongs to the Dynamic series.

Within the shortest possible time from delivery, the machines perform excellent work thanks to the well-trained staff and the good cooperation with the training centres in Linz (Austria, Plasser & Theurer) and in Bingen (Germany, Deutsche Plasser).

First machine in this output category in Poland

The Unimat 09-4x4/4S Dynamic is in a competitive output category. Acquired by Torpol S.A., a Polish track maintenance contractor, it will be used for national and international operations. The experience gained with the Unimat 08-275/3S universal tamping machine performing well since 2008, decisively shaped this new machine. It enables continuous working action and is fitted with both 3-rail lifting and 4-rail tamping. In addition, a dynamic track stabiliser is integrated in the machine. 

New machine in Germany forming the basis for cost-efficient track maintenance

Competitiveness, economic aspects and the positive development tendencies on the German railway market led to Busching-Wagner’s decision to invest in new machines. The company acquired the Unimat 09-4x4/4S together with the USP 2000 C2 ballast plough. The two machines have been fitted and approved for coupled transfer travel (in tandem) for the first time. This means that the drives of both machines can be used. Controlled from the control desk of the respective front machine (tamping machine or ballast plough), the consist travels under own power.

Success right from the start – this machine model meets all expectations

The new Unimat 09-4x4/4S closes the gap between our compact machines and the large universal tamping machines. The first Unimat 09-4x4/4S was delivered to SB Rail in Great Britain, fitted with an integrated dynamic track stabiliser. Other machines operated successfully in Germany by Spitzke, Joseph Hubert and Leonhard Weiss prove the success of the machine concept.

One million tamping insertions

In March 2014, the new Unimat 09-4x4/4S was delivered to Spitzke in Germany. It was the first track maintenance machine in Germany equipped with the new P-IC control system, the DRP data recording processor for digital recording and the rotation speed modulation for the tamping units. Since its delivery, the machine has achieved an enormous output: 1,038,200 tamping insertions, approx. 4,600 engine operating hours and 61,000 kilometres of transfer travel by the end of May 2016.

The main feature of this machine model is stressed by all operators: it meets any requirement possibly existing on plain track as well as in turnouts with tight radii. Further machines for the operation across Europe are already being produced.
