Growing up in an ex-L&Y area, I used to hear boxes commonly referred to as cabins, e.g. by my neighbour (a retired signalman) and by someone I knew at school whose father was a signalman. To this day Parbold box bears the nameboard Parbold Cabin. Was this just an L&Y custom, or was the term used (officially or unofficially) on other companies' lines as well? At the back of my mind is a feeling that the Mersey Railway had boxes lettered Cabin A, B etc.
