  The REM 44ZII - Ballast Distributing and Profiling Machine {II generation} is a second generation high output fully automated REM Ballast Distributing and Profiling Machine, special development and design by R&D Center “REM" with possibility for manufacture at stage zero in a REM plant by request of the client. This is a second generation of REM machine, automated with built – in autonomous systems: laser, for full remote control, for on-line diagnostics during operation, radars, georadars, GPS, 3D control and other REM systems. Our clients obtain a new class of Ballast Distributing and Profiling Machine with 18 month REM warranty, with high trustiness, high reliability and with high range of efficiency of up to 19 km/h.

The REMTECH ballast distributing and profiling machines the REM44ZII, the shoulder ploughs are positioned in front of the ballast crown plough. The shoulder ploughs profile the ballast shoulders and draw ballast up into the ballast crown to distribute it there according to the positioning of the baffle plates. Surplus material lands in the area around the sleeper-ends. Afterwards, the sweeper unit removes the ballast stones left on the sleeper surfaces and, depending on the equipment of the machine, conveys them to the sleeper ends or on a steep conveyor belt into a ballast hopper. 

   The machine has been designed and tested to operate in extremely severe working conditions like continuous loading, high ambient temperature (climate), dust, severe pollution of the ballast prism, night vision windows for operation/screening upon full guarantee of the safety of the servicing personnel through an innovation system of REM Radar. No matter of the modes of operation and load, the automated system for control guarantees the client in real conditions of exploitation on the rail road reaching of the assigned factory – design productivity of screening up to levels of 19km/h {Running speed while working 0-19 km/h}.

  Successful integration in the machine of patents, REM know – how and innovative REM systems for automation, control, diagnostics and securing of the work of the main key units and components (as per individual requirements and needs of each client), give the opportunity to any client to have a unique modern Ballast Distributing and Profiling Machine with customized requirements: with no analogue worldwide as to volume of further upgrading systems and automation. Each additional system gives unique opportunities for expanding of the capabilities of the machine, which generally result in minimum direct participation and engagement of a machine operator of upgrade, control and supervision during work:

 Variable plough equipment
   During work, the centre plough and the two shoulder ploughs are operated fully hydraulically from the workplace in the cabin. Due to the multiple variations of positioning as well as the fact that all ploughs can operate in both directions, it is possible to perform any desired displacement of the ballast..
  Powerful sweeper unit
  The sweeping device removes surplus ballast from the sleeper surfaces and fills the sleeper cribs. It is suspended on the main frame under the cabin between the two axles. Basically, the output of this unit determines the overall output of the machine during track maintenance, because normally the entire ballast bed profiling is carried out in one pass behind the tamping machine. To achieve this, the sweeper unit is equipped with a brush of large diameter and stepless adjustment of the rotating speed to adapt to the prevailing conditions. It is also capable of performing deep sweeping and sweeping work on switches and crossings.   
  Flexible treatment of ballast
  The ballast collected by the sweeper brush can be treated in two ways. Firstly, the sweeper unit is fitted with a transverse conveyor belt onto which the brush throws the ballast. The conveyor belt throws the ballast, as required, to the left or the right of the ballast shoulder. The machine is equipped with a ballast hopper and is able, by simple switch over, to throw the ballast onto an elevator conveyor belt which takes it directly to the hopper. The stored ballast can be used to fill the tamping zones at any time via four discharging outlets with hydraulic flaps. The positioning of these chutes immediately in front of the centre plough guarantees the technologically correct sequence of operation.

 REM 44ZII is used to realize track bed bi-directional ballast distributing and profiling operation through center plough and shoulder plough;
The sleepers sweeping unit can clean the ballast from sleepers, and then send to ballast hopper through conveyor belt. The ballast is supplemented to both sides of rails where necessary;

+REM Georadar Measurements - RGM : Automated system for georadar (ground-penetrating radar) roadbed inspection REM GEOSCANNER is intended to provide the following solutions:
  - determining thickness and lithologic structure of the ballast bed discriminating the fouled subgrade layer and increased moisture areas;
  - localizing the upper boundary of roadbed soils and their lithologic structure;
  - discriminating low coherence areas in the roadbed featured by reduced density and increased moisture;
  - revealing foreign objects in the roadbed and ballast bed, viz., cables, buried track superstructure components (crossties, rails), large stones, etc.
  - localizing engineering facilities;
  - localizing areas with laid geotextile or expanded polystyrene;
  - inspection of quality of the accomplished track overhaul.
  The objective of this method of investigation is to determine the pollution within the ballast bed and the mixture of ballast with the subsoil. It is also possible to locate water traps. The qualitative measurement of the water content in the subsoil enables the existing drainage quality to be assessed. By comparing the condition before and after the rehabilitation, it was possible to make a quality assessment of the formation rehabilitation work performed.

  The REM Georadar Measurements - RGM is state of the art for GPR systems. It is based on more than 20 years of working experience with GPR and it is the product of continuous development and adaptation to the specific requirements of our international railway customers.
  - Survey of tracks of any length or even of the entire railway network.
  - High speed survey of 900 track kilometres per run.
  - 2,000 scans per second.
  - Each channel is controlled separately, allowing even speeds of more than 300 kph.
  - Three or even more longitudinal profiles provide track cross section at any position.
  - Measurement only between sleepers to avoid disturbances.
  - Scan distance between 2 cm and 60 cm for coping with all customer requirements.
  - Antennae frequencies between 100 MHz and 900 MHz for high resolution in all depths.
  - System-embedded positioning radar for accurate allocation of all measuring data along the entire track. Accuracy better than 0.5 m.
  - System-integrated DGPS for reception of world wide satellite systems GPS and GLONASS. Correction data for GPS via GSM or EGNOS for an accuracy better than 0.3 m.
  - Displaying of survey track and all constructions in Google Earth.
  - System-integrated Video-camera for continuous view of survey track.
  - System-specific Viewer-programme for display of the GPR results related to the geotechnical conditions of the track, including Google-Earth-view and Video-camera-pictures.

  The RGM survey provides continuous details of track conditions. Railway engineers obtain important information about:
  - Thickness of track bed and sub-ballast layer.
  - Sections with clean or fouled ballast.
  - Drainage problems in ballast bed and undertrack.
  - Mapping of load-bearing problems (settlements, ballast pockets).
  - Anomalies along the track.

  RGM - Radargram with longitudinal profile of track section
  The picture shows a track section between km 11.100 and km 11.700.
  In that section the ballast has been renewed to a depth of 0.3 m. Below, there is fouled ballast (dark grey layer). Ballast settlements indicate insufficient bearing capacity of the sandy formation. Below the sandy layer, a drilling at km 11.450 is showing peat and clay.

  The picture shows a track section between km 1.300 and km 1.900 (see horizontal axis). The vertical axes represent both depth in m related to top of sleepers and travel time of the waves in nanoseconds.
In that section the ballast has been renewed to a depth of 0.5 m (pale grey layer). Below, there is fouled ballast (dark grey layer). Ballast settlements can be seen between km 1.460 and 1.570. This is an indication for insufficient bearing capacity of the sandy subgrade (yellow layer). Below the sandy formation there is clay to be found. Between km 1.600 and km 1.900 the clay layer is almost adjacent to the ballast bed. In this section, a well working drainage is important. Otherwise water will remain inside the track, leading to eventual stability problems of the track.
  The picture shows crossings at km 1.370 and km 1.870. Drillings have been carried out at km 1.550 and km 1.740. In both cases ground water has been found in a depth of 1.2 m.

  Quality control of track construction
Track construction is always very cost-intensive. That's why at least the result should add up. Our quality control is continuous and exact. And we provide information about:
  - Quality of new ballast (cleanliness).
  - Thickness of track bed and sub-ballast layer.
  - Efficiency of track drainage.
  - Evenness of ballast-bed bottom or sub-ballast layer.
  - Track cross-section.
