High-speed ballast cleaning technology
Ballast contamination is the main cause of track defects and ballast section cleaning is the main source of costs for maintenance of the railway infrastructure.
 
Low productivity of ballast cleaning machines is a deterrent in improving the efficiency of track repair.
  • increase the speed of the ballast cleaning machine during the track repair to up to 750 m/h;
  • increase the capacity and turnover of machines for material logistics with the optimisation of the logistics scheme;
  • increase the efficiency of the entire technological process of repairing the track.

Innovative technologies of track repair

Effective technologies are the vector of PTK Group development
JSCo "Russian Railways" set a task to modernise the transport infrastructure and introduce modern technologies to increase efficiency and optimise costs.
Scientific and Technical Council of JSCo "Russian Railways", including for the development of highspeed and heavy traffic, defined the requirements for advanced technologies for repairing the track, as well as for high-performance track machine complexes.
 
Based on these requirements, the PTK Group together with JSCo "Russian Railways" developed new technologies and technical requirements for track machine complexes, as well as feasibility studies that prove the economic effect of their implementation.
 
On the basis of a new line of machines, a multipurpose track complex for a ballast section has been created. The modular design has unique technical features, allows the use of high-performance machines in various track repair technologies. Our technical solutions have no analogues, that is confirmed by patents.

The economic effect of the introduction of new technologies for repairing the track on the basisof a multipurpose complex is at least 34%
Protective sub-ballast layers formation technology
For the high-speed and heavy traffic organisation, a compacted layer-by-layer protective sub-ballast layer, which enhances the bearing ratio of the roadbed and prevents the contamination of the ballast section, is of particular importance.
The result of technology implementation
  • significant increase in the speed of work (up to 100–150 m/h);
  • optimisation of the logistics scheme due to the organisation of local areas for material storage and preparation;
  • significant reduction in material costs due to the efficient use of secondary materials.

Volumetric-compacted ballast section formation technology
The traditional technology of ballast section formation provides for the need to limit the speed of train traffic with the subsequent increase in speed as additional work is carried out (additional ballasting, straightening and stabilising the track).
  • increase the train speed up to 80 km/h immediately after the repair;
  • reduction in the number of stages of work by eliminating the need of additional ballasting of the ballast section;
  • reduction of costs for current track maintenance, minimisation of local track defects.

The introduction of the Volumetric-compacted ballast section formation technology
will provide a significant reduction in the cost of work,
as well as reducing the time for repairing the track and increasing the speed of traffic
For example, on the length of 1000 meters the time of work on the new technology was reduced to 697 minutes compared to 1093 minutes according to the existing technology.

Local storage areas organisation
The main reason for high costs and a long period of track work is the remoteness of places for loading ballast materials.
The result of technology implementation
  • сontinuity of work of complexes, optimisation of logistics;
  • efficient use of secondary materials.
The scheme of local bases organisation
With considering the existing competencies, we create effective solutions for the logistics organisation in new technologies for repairing the track.
Tasks
  • organisation of temporary local bases within 30 km from the site of work;
  • delivery of materials with the help of new quickly loaded carriages for the material logistics MML-88.
