ONE of the last of Scotland's sets of Victorian railway signals, which have controlled trains on the main line between Edinburgh and Perth for more than 100 years, are to be replaced by electric "traffic lights".

The former Caledonian Railway Company semaphore arm signals at Stirling Railway Station will be taken out of service later this year.

The signals are being replaced as part of a modernisation of the railway in central Scotland. They are so rare the Category A-listed signals will be displayed within the station as a museum piece.

Sempahore signals were one of the earliest forms of fixed railway signal.
