Rail Control Solution
With rail wagons it is not safe and normally not permitted for personnel to cross from one side of a series of wagons to the other side in order to operate a hatch, and in some circumstances the hatches need to also be operated from other locations e.g. top, on the wagons. There may also be a requirement for a higher operating pressure. The rail Control Solution includes a hatch which can operate up to 2.5 Bars and which can be controlled independently from up to four locations on the rail wagon.
