Pontiac Michigan turnaround

Hello. I just have a quick question about the wolverine terminal in Pontiac Michigan. Just from looking at Google maps, it appears that there is no Y or any other way to turn the train around. Likewise, most wolverine trains run with the a locomotive in the front and back. However, sometimes I see a wolverine with just a locomotive in the front. How do they turn those trains around in Pontiac?



I also found this. In the video, the departing train leaves one of its locomotives behind. Is there a reason for this? What exactly is going on here?

Thanks for your help.

I don't know how they do their operations, but, looking at Google Maps, I do see a wye a couple of miles northwest, just beyond what looks like a freight yard.

Pretty much, the back the train up to the nearest wye & turn it there.
