The Wellington, Grey and Bruce Railway (WG&BR) was a railway in Ontario, Canada. It ran roughly northwest from Guelph (in Wellington County) to the port town of Southampton (in Bruce County) on Lake Huron, a distance of 101 miles (163 km). It also had a 66-mile (106 km) branch line splitting off at Palmerston and running roughly westward to Kincardine, another port town. A branch running south from Southampton was built during the construction of the Bruce Nuclear Generating Station in the 1970s.
