СЧ-1000 ballast cleaning machine is a self-propelled two-section track machine, it is designed for cleaning from ballast contaminants at the waysides, station tracks as well as near the platforms with the preliminary lifting and displacement of the railway track. The contaminants are removed aside from the track or into the special rolling stock. The cleaned ballast is distributed under the track skeleton. The ballast can be also cut out (without cleaning).
The works are carried out at any time of the day on straight and curved single-track and multi-track sections of the continuous welded rails and jointed track, of wooden or reinforced concrete sleepers of ordinary length, with all kinds of rail connections (spike-fastened, screwed, terminal-bolted).
The machine is a self-propelled two-section track machine. The sections are firmly coupled together (can be easy disconnected if necessary). The machine is mounted on four bogies (two traction bogies and two running ones). Both parts of the machine are interconnected by electric, pneumatic and hydraulic connectors.

- driver’s cab with a fully-featured station for one-way movement
In the operating mode, the machine performs:
- cutting and cleaning from ballast contaminants at the waysides, station tracks including near the platforms with the preliminary lifting and displacement of the railway track, removal of contaminants aside from the track or to a special rolling stock;
- laying of geotextile between the railway roadbed (cut surface) and a ballast layer, which is covered;
- laying of cleaned ballast under the track skeleton;
- cleaning of fasteners after ballast laying.
In transport mode, the machine moves as a self-propelled transport unit. The machine can be transported unattended.
The machine has additional technological functions:
- the ballast screen is set to the transverse horizontal position automatically during operation;
- the machine is equipped with a measuring system for recording operation parameters;
- cleaning of fasteners after ballast laying;
- the machine lays geotextile between the railway roadbed (cut surface) and a ballast layer, which is covered;
- the machine is equipped with a camera system and industrial TV to monitor the process from the operating cabin.
