As everyone knows, Metra prints out special schedules for major summertime events (i.e., the Taste, and such) and in most cases, the details are available online. Sometimes though, other routes will have additional service that isn't mentioned on the website; in fact, I recall last year that extra service was run on the Burlington for some event, don't remember what; but it wasn't announced until a day in advance. Likewise with the recent Lollapalooza fest, extra trains were run on the Rock, without a reference to such on Metra's website. Are these announcements of special "unpublished" service always done on short notice like that, or is it just on a "need to know" basis?
