With at the time, a bold forecast of heavy grain traffic in Canada, the decision was made to bring in reinforcements, i.e., pull power out of storage, which meant all but about half a dozen 8-40CM's were reactivated. BCOL 4604 was one of the chosen ones as it was pulled out of Homewood and put back in service. While the grain was not as heavy as expected, there has been an upturn in traffic recently that seems to have justified the revival. While it was not on grain when I saw it, it was leading the hottest eastbound train on the CN Flint Sub, Q148. With temps in the teens and winds comparable, the cold was definitely biting at my hands while the stack train flew by, but seeing a barn back from the brink, is definitely worth the cold fingers.
