North London Society of Model Engineers - Somersault Signal
North London Society of Model Engineers - Somersault Signal
A Great Northern Railway 'somersault signal' - this gives engine drivers an indication if it is safe to drive past the 'steaming bay' just out of sight behind the trees. (The steaming bay is where the locomotives are prepared for running - the model equivalent of an engine shed.)
Somersault signals were developed by the Great Northern to replace signals whose arms were pivoted in a slot in the post - these tended to freeze in wintery weather and led in 1876 to a serious accident at Abbot's Ripton where 13 people were killed and many injured due to false clear signals.
