Stop!!! The iconic beauty of the semaphore railway signal. Becoming very rare on the main rail network, but still found working on heritage rail lines. Also, no model railway is complete without them!!#uktrainspotting #trains #diesellocomotive #britishrailways #railway #railways #trainspotting #railroad #modelrailway | Adrian Watson

Before radio, visual line of sight signalling with signal lamps, flags, and these physical semaphore devices were used. The concept of signaling for long distance communication is ancient and used extensively during earlier conflicts like the Napoleonic era. A version of semaphore devices survived in modern time in the form of railway signals. #WW1 #WWI #ww1history #logistics #capcut | This Day In WWI
