Cowley Bridge Junction is a miniature
working signal box that can be taken to schools and
exhibitions to demonstrate mechanical signalling principles.
As such, it acts as an ambassador for the overall Romsey
Signal Box project.
The famous junction near Exeter was
chosen as the basis for the miniature box because it offers
intensive working over a track layout that is interesting
without being too large or complicated. Capable of being
transported, Cowley Bridge comprises three parts:
·The miniature lever frame
·A full-size block shelf with all its
· A simulator computer that imitates the
neighbouring boxes, and enables the operator to exchange
messages with them.
