St Paul Union Station

Was watching the St. Paul Union station web cam today. I see two CP engines towing an E unit, a Soo Line caboose, and a Soo Line Gp30. A few minutes later the CP engines are pushing the consist into Union Station, then pulled the E unit forward where it can be seen as I write this. The track they used is not the track the Empire Builder uses. Anyone know what is going on?

That W&S livery looks mighty nice. Kind of sad to give it original Milw. paint scheme it never had in the first place.
