THE SIGNAL BOX

STANDING AT THE PEG, BOBBY
A glossary of signalling slang

by John Hinson

"Standing at the peg, Bobby" means quite a bit to a signalman, but the layman could not possibly have a clue as to what it might mean.

This glossary explains the meanings of terms like this, giving information (where possible) as to how the terms came about. Many terms are regional, and often stem back to pre-grouping days and vary between former company's territories.

I would welcome any suggested additions to this section, but I would stress that this is a general glossary and I do not intend to include very localised jargon.
