This chunk of staging is "across the river" from Saint Paul, as you head west in the Mississippi River valley. The tracks leading here are joint Milwaukee Road and Chicago,St. Paul, Minneapolis & Omaha (C&NW), with Milwaukee trains heading into S.E. Minnesota and Omaha trains heading to Mankato and on to Omaha.
There are seven regular tracks here, with one additional "long track". While I'm sure this is sufficient in quantity, they may not be long enough. Their short length is made up for by the fact that this is a tertiary staging yard (more of an afterthought really).
The brackets you see are supporting the upper level in this area, which will hold the line to the Ford plant. This benchwork & tracks are the next major piece of construction.
