From the marker:
In 1920 a rail link pushed westward from Midway to transport the riches of the Kootenays, Boundary, and Similkameen to the coast via an all-Canadian route. Andrew McCulloch's engineering marvel, the Kettle Valley Railway, crossed three mountain ranges, traversed 500 kilometres, and became the lifeline of the Southern Interior until abandoned after sixty years. Today the KVR is reborn as part of the Trans Canada Trail.
