NUMBER 90 I had created a reply to your post but it wound up in cyber space!!
the division street wye is where camera 2 resides and you can view both mainlines as well as the other 2 legs of the wye both going to or from the StPaul union depot area. early morning from sunrise is kind of hard as sun is glaring into camera's lens! in the middle of the wye great northern used to have a small 2 door diesel building they kept passenger aba f3 diesels there in case the empire builder had a broken unit they would swap the bad unit/s out.
camera 1 is on think on the west side of depot and gives the view of the empire builder as well as freight traffic heading west or east and it also shows the very old lift bridge that union pacific uses to cross the mississippi river to gain access to a yard on south side of the river.
heading east away from division street wye are the remnants of the Burlington yards also the Chicago northwestern and the Milwaukee road engine service area and still standing roundhouse.
if you use google earth there is an old swing bridge still in operation south of the old airport on south side of the mississippi river it is another way for union pacific to gain access to the yard as they do from the depot bridge.
many eons ago the rock island actually was on that side of the river as my mother would talk of steam engines shaking her childhood home back in the 1930's.
there is a walking area where you can park and walk to where the swing bridge is and I was able to get within a block of it and was lucky to watch two up freights cross it!
hope this information helps identify areas you can watch I miss these cameras as they are my link to a childhood of many decades ago I can remember the switch towers and all the metal rods that moved the switch points ahhh those were the days when you could walk around and as long as we stayed out of harms way no one told us to leave a more simpler time then!
