The Dow "Chemical Special" was a regular movement over our division of Chessie during my time in Saginaw. Not sure what day it left Freeport, TX, but it normally arrived in Grand Rapids every Sunday and then ran north to Baldwin where we took over the dispatching from Saginaw. The whole train was set off at Dean Yard in Midland and then lite power into Saginaw. On Thursday afternoons, lite power was dispatched from Saginaw to pick up the empty train for movement back west and south. For a time, after the Ludington Sub was severed between Baldwin and Midland, the train ran east out of Chicago via the former B&O to Toledo, and then north to Saginaw and Midland. At some point, the routing changed to CN out of Chicago to Durand and handed off to the HESR for movement to Midland. Needless to say, we were always relieved when this train made it over the road without incident!
