Unpublished paper, 'A system of train-signalling, by which also disabled trains may telegraph for assistance without the aid of portable apparatus' by Charles Walker

Reference number: AP/39/20

Date: 09 March 1857

Description

Walker explains that 'in the early days of telegraphy, messages were sent and trains were signalled on the same wires, [and] no facilities existed for reducing the apparatus employed for the latter purpose, to a simple form. The case is now becoming different, special wires being largely devoted to train signals'. He describes a system of electromagnets and bells which can be used in train signalling.

Includes one page of figures and photographs of Walker's bell system.
