Here's a photo captured at North Bay's Locomotive Shops in April 2005. The units seen here are classic SD40-2's 1736 and 1731. These units have been set in storage alongside the Locomotive Shop for quite some time but, as the photo shows, the units have actually been moved. This begged the question, "Are these units returning to regular ONR freight service?".
The answer to that question, which was a big fat "No", arrived in October 2005 when the units were sold to a company known as Progress Rail Services who carries "PURX" AAR reporting marks.
