?Upcoming train shows in the Twin Cities?

You are right regarding the train show at Century College.  The Great Upper Midwest Train Show will be held on November 17th at Century College.  Admission is $4, with kids under 12 free.

Although not in the Twin Cities, there is the Granite City Train Show at the National Guard Armory in St. Cloud on December 1st ($3 admission).  I have not been to this one, but thought I'd mention it as well.
