Semaphore Signals

Semaphore Signals give an indication to the driver of a train using a movable arm, usually operated by an arrangement of pulleys and wires from the signal box. Most railways used some form of semaphore signalling until the mid-20th century, but since then they have been replaced in most places by colour-light signals, which are more flexible and cheaper to operate and maintain. Germany is one of the few places in Europe where semaphore installations are still reasonably common.
