Based on last year's event, some of the locomotives that were on display at National Train Day 2012 at CUS were also on display at Franklin Park Railroad Days. I am unaware if that will be the case this year, however, there seems to be a Metra cab car that is on display every year at the event.
Viewing of the locomotives takes place from 10-3 this Saturday I heard.
Hope this information is helpful. Cheers.
