Construction of the track began in 1910, with the building of a bridge over the Saskatchewan River at The Pas (just northwest of GZ). Canadian Northern Railway (which would later merge with other rail companies to form Canadian National Railway) sought to build a track from just north of The Pas to a seaport at the mouth of the Nelson River. Construction of the line to Port Nelson continued until World War One, when supplies were diverted to the war effort in Europe. After the war ended, the political will to finish the line waned, and the track sat incomplete for several years.
The line had been completed to Kettle Rapids, but when interest was renewed in the line, the decision was made to use Churchill as the terminus, at the mouth of that town's namesake river. Modern maps bear witness to the abrupt change of course the Hudson Bay Railway took when it turned away from Port Nelson. The rail finally made it to the ocean on March 29, 1929, nearly two decades after construction had begun.
Today, the Hudson Bay Railway includes branch lines to Flin Flon and Lynn Lake, and is administered by a rail company of the same name. Its headquarters are here in The Pas, near the intersection of 7th Street and PTH 10.
