Based on this article, how did the existence of trains impact the development of Roche Percee?

Context: In 1872 the Boundary Commission travelled through this area while surveying the border between Canada and the United States. During the 1874 March West trek of the North-West Mounted Police, the force established its first camp at this location. The community began being served by the Soo Line in 1893, permitting the coal mines in the region to become operational. Roche Percée incorporated as a village on January 12, 1909.

Answer: The area that became Roche Percee was impacted by trains when the Soo Line connected the village to a train line. This train line allowed for coal mining in the region to develop by providing access for transporting coal. After the development of these coal mines, the area was eventually able to grow enough to become incorporated as a village.
