Jargon Buster
The jargon buster aims to give simple, plain English explanations of typical words and phrases used in the rail industry – to help us all understand what we read or hear day-to-day.
If you’ve heard a word or phrase you don’t know, check to see if it’s on the list below. If it isn’t, please send it in, giving as much context as possible. We will do our best to find out what it means and publish an explanation here.
You can also add terms yourself. If you do, please include the word or phrase itself, plus a short explanation of what it means and when it might be used.
There are also terms used on this site as defined in Network Rail's Infrastructure Investment's organisation that maybe of more general use and help you in your understanding.
