 The CNoR, GTPR, and NTR were nationalized to form the Canadian National Railway, which currently is now Canada's largest transcontinental railway, with lines running all the way from the Pacific Coast to the Atlantic Coast.The first railroad to directly connect two oceans (although not by crossing a broad "continental" land mass) was the Panama Rail Road.Opened in 1855, this line was designated instead as an "inter-oceanic" railroad crossing Country at its narrowest point, the Isthmus of Panama, when that area was still part of Colombia.
