There will be a huge tunnel (‘the station square’) under all tracks and the distinctive main building will be completely renovated and restored to its original state and colours as much as possible. Because this is also a precise matter for the National Office, Arjan van Lochem’s (colour) technical experience comes in handy.

Anker Stuy Coatings’ account manager brought the necessary colour charts this Tuesday morning. However, it is impossible to find a complete “match” for all the (transparent) colours. But that’s not a problem. “As long as we know what type of wood was used, our colour lab can reproduce it,” Arjan says. “Even if multiple layers are applied. I will send Rolinka some options soon.”

Rolinka Otten, as conservation advisor on behalf of NS Stations Property, is watching Arjan with a critical eye: “We want to deliver the station in as original a state as possible, including the original paint colours.” When Arjan carefully scratches off the layers of paint with a knife, no less than five colours emerge on a window frame: dark purple (the top layer), creamy white, dark green, dark brown and finally the original colour: a clear coat.

The white part in particular stands out, but is quickly explained by Rolinka. “Don’t ask me why, but it was a trend in the 1970s to paint everything white or gray.” If it were up to Rolinka, the window frame would go back to its original state. And so with a clear coat, bringing out the natural beauty of the oak again.
