Disc signals were a type of signal used by the Festiniog Railway from the mid 19th century until the 1920s. They were used as auxiliary signals (a near equivalent to modern distant signals). However, their exact use was very dependent on context: a disc preceding a 'modern' semaphore signal would be regarded as a distant, yet by the 1920s the surviving disc Signals were largely regarded as 'stop' signals, where not pure level crossing signals.
