These attributes allow us to achieve great results while working on tightlyspaced railways and under the immense time pressure often associated with these projects. One innovation is the ‘steel highway’, a system with large, extra wide steel plates. It protects the soil underneath, is environmentally friendly and can be installed quickly. Other methods especially developed for railway constructions are the side-feeder on the shovel and the special bulldozer blade. Pioneering solutions are typical Martens en Van Oord solutions.
