On 29 September 2007 three gantries with new signals were erected between Aachen Hbf and Rothe Erde with the aid of a Super Puma helicopter. In this pictures the workers are attaching the distant signal repeater for the medium track, while the one for the left track is already mounted (the one for the right track has a normal mast and was erected long before). In the background another new gantry with some old signals underneath is visible, it will carry the associated main signals (the one for the left track is already mounted, the one for the medium track is still missing).
