Amtrak Train 350 is heading past the yard office in Pontiac after wying the train. A power swap with Train 353 made this move necessary for 355's trip to Chicago.
Amtrak has three routes that connect Michigan with Chicago, but none to the East or South. The routes are: Wolverine - Pontiac - Chicago; Blue Water - Port Huron - Chicago, and Pere Marquette - Grand Rapids - Chicago.
