TRACK TECHNOLOGY


Track maintenance using systems – MDZ Mechanised Maintenance Trains


Rail transport of passengers and freight demands railway track of the highest quality and perfection. Future-orientated technologies and up-to-date machines must be deployed to achieve economical maintenance of the track, argues Alexander Leser of Plasser & Theurer.


P


lasser & Theurer offers for all types of rail network the right design of the MDZ


mechanised maintenance train composed of machines, coordinated in terms of speed and output.


An optimum interaction of the technologies used will determine the achievable working output, the quality of work and ultimately the cost efficiency. Using Plasser & Theurer mechanised maintenance trains, the working operations are performed in the technologically correct sequence: lifting, lining,


tamping,


stabilising and profiling the ballast cross- section.


MDZ 3000


Many years of experience with four-sleeper tamping show that the high expectations have been confirmed in every possible way. The MDZ 3000 now in operation comprises the four-sleeper tamping machine with integrated track stabilisation – the 09-4X Dynamic Tamping Express – usually in combination with the presently most up-to-date ballast management system, the BDS 2000 Ballast Distribution System.


This new machine combination, the MDZ 3000 made by Plasser & Theurer, has reached a new dimension as regards the high output and working speed of the MDZ. Both machines are coordinated ideally in terms of work output, travelling speed and setting-up times. The uniform,


simultaneous, homogeneous and


complete execution of the work achieves an improved quality of the work performed.


The Ballast Distributing System enables continuous working action and, thanks to the


The three-sleeper tamping technology with dynamic track stabilisation is an international success. Since 2001 many railway authorities around the world have been utilising the advantages of this machine for scheduled maintenance work.


Due to the fact that a longer section of track (three sleepers) is treated per tamping cycle, it was possible to raise the quality of the work performed and therefore the uniformity.


An SSP/USP machine from the 2000 series is an ideal match for the tamping machine and produces a finished track behind the 09-3X Dynamic.


An excellent initial quality is achieved after track geometry correction by carrying out ballast distribution, profiling and stabilising.


The Plasser 08-16 split head tamping machine is a compact, all-round machine which has the main advantages and qualities of the heavy-duty tamping machines in the Plasser & Theurer range of machines.


The PBR 400 ballast distributing and profiling machine, with a front plough, two shoulder ploughs and a sweeper unit ideally matches this tamping machine category.


Another option is the DGS 62 N, which achieves improved track geometry through dynamic track stabilisation, thus extending the service life of the track.

specific redistribution of ballast, reduces the need for new ballast by up to 60%. The existing storage capacity of around 20m³ can be enlarged by adding MFS 100 material conveyor and hopper units to the middle of the machine.


MDZ 2000


A further variation of the MDZ is the combination of a three-sleeper tamping machine with integrated track stabilisation, the 09-3X Dynamic Tamping Express, and a continuous action stabilising and profiling machine from the SSP/USP series. These two machines also match one another in their work output.


It brings not only savings in personnel but also savings in the number of machines deployed and therefore in many instances also simpler worksite logistics.


MDZ for small track networks or commuter rail networks


The changeover from manual work to


mechanised work will result in considerable savings. The cost-efficiency of well-proven machine technologies is confirmed even on small track networks.


For these requirements, Plasser & Theurer can also offer MDZ machine combinations.
