OpenRailwayMap/Work Rules in North America

 | This page is under construction and is incomplete; there is a significant amount of data to cover because of the large number of railroads in North America: please contribute! |
Operating Rulebooks
This page contains information on the various common operating rulebooks in Canada, Mexico, and the US, in order to help complete the workrules=* tag. This data is very much a work in progress.
Definitive OpenRailwayMap (ORM) tagging conventions are found at OpenRailwayMap/Tagging. For general guidance on tagging specific to North American railroads, see OpenRailwayMap/Tagging in North America. For general information on the US railway mapping effort, see United States/Railroads, which contains some information also useful in Canada and Mexico.
NORAC
The Northeast Operating Rules Advisory Committee is both a rulebook and the organization that defines said rulebook. NORAC was formed in 1985 to create a common rulebook for the Northeast; operations became more complicated after the creation of Amtrak and Conrail, and after state and municipal agencies took over commuter rail operation and ownership. As such, NORAC has more ways to represent the same signal rule than any other set of operating rules in the United States. NORAC is a speed signalling system, and has the most speed signalling than any other rulebook. Those using NORAC have to use the rulebook in its entirety, with no additional rules. NORAC 12th edition is current, effective 1 January 2024.

CROR
The Canadian Rail Operating Rules (CROR) is a set of operating rules for railroads in Canada. The CROR is used by every Canadian railway. The current version is the one dated 9 May2022.
The CROR only dictates what light signals should look like, and leaves the track-side signs up to the individual operators. The signs are similar across the different operators
