Three interesting signals seen in Cologne on 1 November 2001. They are placed
at the western entrance of the Hohenzollern bridge. They seem to be distant
signal repeaters of the
Hp
colour light systemwith compact heads, mounted directly on the ground.
This is the only case of ground-mounted "main" signals (means: signals for
train movements, not for shunting) I know.
