Foreign Roads

New South Wales Railways

NORAC roads (Northeast Operating Rules Advisory Committee)

NORAC was formed in January 1985 with the first five roads and Metro North.  MN later backed out.  The Long Island, B&M, and P&W joined at the second meeting in May 1985.  The rules became effective January 1, 1987.  For more info, check out: http://trains.com/trn/default.aspx?c=a&id=230

For a very nice interactive signal display of the NORAC rules, check out this page

CROR (Canadian Railway Operating Rules)

Railroads in Canada follow these rules, and almost all legacy installations use searchlight signals.  Newer installations, and replacement are seeing color light signals because of cost and ease of maintenance.  A few semaphores are supposed to still be around.

The CROR Rules

CORA roads (Chicago Operating Rules Association):
