[Isabella Muir]

Hi everyone - I am hoping that someone will be able to help with some research I am doing for a novel. The novel is the fourth in a series of crime mysteries, set in the late 1960s in Sussex, England.

I was wondering about the operation of signals at that time and in that location. How did the unmanned railway crossings operate? What made the barriers open and close? Was it an automatic connection for another barrier further up the line?

Any information you can provide will be very useful.

Thanks in advance
