Signal Fact 33
Somersault sempahore signals, centre balanced, were developed as a response to the Abbots Ripton collision of 1876 when snow had interfered with the correct operation of slotted post signals.
They were adopted by the Great Northern Railway, Belfast & Northern Counties Railway and Midland & Great Northern Joint Railway among a few others, including Australia.
