Route indicators

Route indicators

In single and double light colour light signalled territory, route indicators on running signals indicate, in most cases, the turnout route.

If the signal displays a PROCEED indication, the route indicator shows:

• letters, usually related to the name of a line, as in ‘S’ for Suburban, and ‘UM’ for Up Main, or
• numbers, usually referring to the number of a station platform, as in ‘3’ for the line beside Platform 3.

Route indicators on shunting signals or co-acting signals may show:

• a running line turnout route, or
• a shunting route.
