Further information

The URM 700-2 universal ballast cleaning machine is the new multitalent for ballast bed cleaning. Unique on the world market, its innovative technology enables Plasser & Theurer to fill a market niche by offering full turnout service.

Most contracting companies do not offer special services such as an on-track turnout maintenance system. Plasser & Theurer has taken full turnout service to a new level. Austrian Federal Railways (ÖBB) has been able to use this technology.

New offer for ballast cleaning in turnouts

Turnouts place particular demands on maintenance. Due to their key function in the track system, they are considered essential infrastructure components. Turnout installations on modern high-capacity lines consist of concrete sleepers, sensitive drive and control systems and heavy rail profiles. When maintaining turnouts, these expensive components must be handled with utmost precision. Cost-efficiency is the goal - not only when maintaining plain line track, but even more so when maintaining turnouts which often affects two tracks at the same time. The duration of track closures is a key factor, particularly for main-line railways.

The URM 700-2 offers decisive advantages when managing tight schedules for turnout maintenance. There is no need to remove and reinstall the turnout. Both ballast cleaning and tamping in turnouts can be completed during one single shift. As soon as the work has been completed, the track section can be reopened for traffic. For this reason, the Austrian Federal Railways have opted for employing this system on their priority routes. During maintenance with the URM 700-2, the adjacent track remains open for traffic which reduces track possessions to a minimum. This is impossible when employing conventional methods involving excavators and cranes.

Continuous-action turnout cleaning

Our URM 700-2 ballast cleaning machine is the core technology for turnout maintenance. This machine makes it possible to clean the ballast bed without removing the turnout. Moreover, it allows for continuous working progress. In addition, it cleans the ballast shoulders. The machine is also suited for maintaining large high-speed turnouts with movable-point frog. Another advantage is that sections of track at connecting tracks and between turnouts can be cleaned in one pass.

Thanks to the fast and independent installation and removal of the excavating unit, the URM 700-2 works cost-efficiently on short sections of track.

  • Short set-up times
  • No need to cut the rails, neither at the start nor at the end of work.
  • No full track closures - the time required for ballast cleaning in turnouts is reduced significantly.

This is exactly what railway administrations require: fast, safe and high-quality ballast cleaning in turnouts without long track possessions.

Optimal results for many trains to come

After the URM 700-2 has completed its work, our all-rounder for track maintenance enters the picture to ensure optimal geometrical quality of the turnouts. The Unimat 09475/4S N-Dynamic turnout and track maintenance machine combines the functions of three machines: 3-rail lifting and 4-rail tamping, profiling, stabilising and control measuring. A unique feature makes the Unimat 09-475/4S N-Dynamic stand out: it can also ballast the tamping zones. Full turnout service including the ballasting step can be performed within a single track possession. Traffic on the adjacent track continues without interruption which minimises operational hindrances.
