A number of club members model the same geographical area, Wisconsin. This gives the members the opportunity to run a variety of trains that are prototypically correct for a specific time period like Soo Line, Milwaukee Road, and Chicago & North Western. Members of our club recently held a Wisconsin Day 1984-1985 Themed Operating Session "TOS". TOS limits the era of equipment that can be operated during the session so that only prototypically correct trains are operating. This was our club's inagural TOS, hopefully there will be more in the future.
