St Charles Railroadiana Shows

I'm from out of town, but see that there are not one, but two Railroad shows in St Charles on successive weekends this month. I will be visiting the area and was wondering if anyone could advise me on how extensive each show was. I'm interested in railroadiana - timetables and books, especially. Any suggestions?

I'm not too familiar with the other event, but next Sunday's show (6/12) being held at the Kane county fairgrounds has some pretty good stuff, and is definitely worth a visit. A good mix of books and videos, lots of CNW, Milwaukee, Soo, and CGW memorabilia, to name a few. Also a great source of old commuter rail schedules, from the Metra era as well as those of the legacy roads, and is one of the main reasons I've been attending the event annually for the last several years now...
