Four simultaneous Amtrak Movements. On the far left, an inbound Illinois Zephyr. On the left, an inbound Michigan service train approaches CUS, in the front/center, 3 light locomotives awaiting switching into the diesel facility, and on the right, a terminated train (looks like the Capitol Limited, perhaps) backing through the wash. Out of sight to the left, a northbound BNSF coal train occupies one of the mains, so these Amtrak trains are all taking turns with the second.
