A main signal and a distant signal of the
semaphore
system at the left track in Aachen Rothe-Erde. These semaphores were
newly(!) errected in march 2001 to allow bidirectional operation to Stolberg.
They are no more marked as invalid, but note that the distant signal has no
post plate. I'm not shure if bidirectional operation is already in use by now.
In order not to be covered by the roof, the signals were placed on the left. In
the background the mechanical signalbox can be seen.
