On 22 May 2002, the remaining seven of the eight containers forming the new
electronic signalbox (elektronisches Stellwerk, ESTW) in Düren at the end
of the upgraded line from Cologne
(<a href="http://www-users.rwth-aachen.de/christoph.schmitz2/strecke/strecke.html">ABS 4</a>)
were lifted into position. The first container of that day is just placed next
to a container that was put there some days earlier.
