When you build a diamond mine in the far north, you have to supply power to it. Seen here is a load of untreated poles, complete with buffers, being switched off of a 514 March 2006. These poles will head to Northlands in order to be treated via 414. Once treated they'll come back through and head north to become part of a pole line which will run from the Otter Rapids Dam to the De Beers Victor Diamond Mine.
