At most Metra stations that have platforms on both sides of the tracks in double (or triple) track territory, the station platform signs include train direction; i.e., "To Chicago, or "From Chicago"; depending on whether or not Metra (or the host railroad) generally runs this particular line left or right-handed. During my annual railfan trip on NC yesterday, I noticed that the platform signage at stations in double track territory had the directional information crossed out, or taped over. While I would guess most rush hour trains on any given day would berth at the same platform, off-peak service now seems to be a little more random, where trains will just "get in where they fit in", and take any track that happens to be open. This became evident while riding 116 into downtown, because I noticed that we ran left-handed north of Deval, then right-handed south of there to B12. Also, this route, like UP/W, is prone to many freight train interference delays, and 116 seems to get spiked more than most, but yesterday's train actually arrived CUS three minutes early. Overall, it was a pretty nice ride on a beautiful day...
