By far the largest part of the HSL line is combined with already existing infrastructure, or runs underground through a tunnel. Only for a relatively small part of its route does the track cut through the landscape by itself. Were the separate line re-joins a corridor of other infrastructure, there is sometimes a ‘leftover corner’, or overhoek, created. These are often triangular parcels, less than ideal for agricultural use or commercial building plots. Sometimes these leftover spaces serve as spoils depots, where surplus earth from construction work for the HSL can be stored. These sites have been assigned the status of ‘transitional zones’ and are expected to contribute to the high-speed line fitting smoothly into the landscape. As a result, they can provide added value for the areas around them.
In 2003 Atelier HSL organised an open competition for a number of ‘leftover places’ along the route of the HSL-South. Le Fèvre’s project lies at the point where the Schiphol line branches off in the community of Haarlemmermeer, Overhoek 207/HSL/Schiphol line. The rising height of the track bed largely blocks out a view of the spoils depot. However, there is a good view of the site from both the HSL trains as well as normal trains.
The architect’s proposal was to plant rows of trees in this triangle, running at right angles to the HSL line. The grid produces two effects: an accelerating (or decelerating) effect resulting from the diminishing (or increasing) distance between the rows of trees, and a turning effect created by the changing angle at which the rows are seen.
