Caption: 579 will travel up the Vegreville Syb, to St Paul Junction, where it will run up the Coronado sub to Kerensky where it will diverge onto the Lac LaBiche Sub. from there it will go to Boyle, where it will veer off again to go up the newish 24 mile AlPac Spur to switch out the OSB plant. Here, it is leaving the easternmost tracks of Walker Yard. The leftmost track is the Walker Yard Bypass track. I think I see two such tracks on recent Google views.
