Other than seeing the normal Metra and Amtrak trains, one gets to see the Y moves of regional and LD trains. But why do you see Amtrak back up and pull forward, only to see the consist back up again in view and pull forward again?

And what's the speed on that turn to CHI? The Amtrak trains taking the Skyline are zipping along going backwards into and from the station.

The triple track curve linking BNSF's Chicago sub with Amtrak terminal has a MAS of 30mph. Applies only to MT1 & MT2; track 3 is part of the wye, which is 10mph of course.

Nice cam, btw...

Minor nitpick: do you mean Airline, instead of Skyline?
