The rear part of the Plasser & Theurer 08-475 Unimat 4S ballast tamper of
Kölngleis seen at the new overtaking station Dorsfeld (on Cologne-Aachen)
on 8 August 2001. Two small wheelsets that should be for measuring purposes can
be seen, one is next to the bogie on the right and the other is under the
two-axled section. The big device further left seems to be intended to reshape
the trackbed, it was not in use here. For travelling against the work direction
there is a driver cab at the rear end.
