Catenary works in Horrem (on Cologne-Aachen) on 16 December 2001. The catenary
is built while the track is still partly missing. So the work train with the
drums of wire is parked at the end of the track, and the contact wire is pulled
into place by this skylift operating from another track. The worker just
inserts the wire into the pulley that was attached for this operation. The
messenger wire is already in place.
