1 Ballast Under Cutter

2

3 The Stobart Rail Ballast Under Cutters and the process in which they are used has been developed and improved so that ballast can be excavated and replenished without the requirement to remove the track from the infrastructure. The machines working alongside road rail excavators and a team of highly qualified operators can efficiently remove ballast from underneath the following: Plain line Single line Switches and crossings 3rd and 4th rail They can also be used for: Track lowering Wet beds Removal of contaminated ballast Applying cross fall to the formation Improvement of drainage Capable of removing spoil at 70m² per hour and at a depth of up to 350mm below bottom of sleeper. This method has proven to be a cost effective way of improving the infrastructure without the need for major disruption caused by time consuming blockades where the track has to be removed to allow ballast removal by conventional methods. To enhance the procedure used, these machines can be delivered to remote accesses using Stobart Rail specialised road transport where they can be on track using level crossings or approved RRAP s thus removing the complex planning required to get plant to site via the rail infrastructure. 3

4 Driver comfort and control W175 Machine has been designed with driver comfort and machine control being paramount. The operator can select every machine command from a sitting position and can also view the whole operation from the cab. The cab in the earlier machine W147 has been re-designed to improve operator comfort, machine control and vision. 4

5 Conveyor system Complex conveyor system can discharge the spoil throughout a 110 swathe either into a train onto the cess or into a Unimog towing rail trailers and spoil boxes. The swing conveyor on the end of the main unit reduces spillage of the spoil during the transition between rail wagons. Spoil Removal Wheel The Ballast Under Cutter bar and spoil removal wheel can transit spoil from under the track, through the conveyor system and onto a rail wagon at a production rate of approximately15-20 metres per hour depending on ground conditions. 5

6 Removing spoil and ballast The spoil/ballast can be removed from below the track up to 350mm below sleeper base. The machine also has the facility of putting a cross fall on the formation to assist drainage and excavation on canted rail. As the ballast is removed from under the sleepers with the cutter bar the formation is left perfectly level to allow if required a membrane to be placed in situ prior to the ballast being replaced.

7 Support The support team and plant that work with the Under Cutter include the following. RRV trenching in front of the Ballast Under Cutter. RRRV with large Clam Shell following the Under Cutter to replace ballast. RRV fitted with a Tamping Bank to compact the ballast prior to a main line tamper following through. A team of experienced operators both on the machines and on the ground to ensure the track geometry is maintained whilst the work is in progress. 7

8 Safety features Safety features include the facility of setting up a trip wire, protected exclusion zone and multiple emergency stops to protect operatives from the cutter bar and other moving parts. 8

9 Specialist transport Stobart Rail have our own fleet of specialist transport that are capable of transporting the Ballast Under Cutters to site by road, adapter rails allow the machine to on/off track at RRAPs and level crossings. 9
