(n.) Any group of monsters playing "follow the leader" after a single person or group of persons. People noted for causing numerous trains are often titled "engineers." Being killed by someone else's train is "trained" or "run over". Stopping someone else's train is "derailing". A large train that causes a number of fatalities is called a "trainwreck." Places noted for having trains come through are "train tracks", e.g. "Don't complain about trains if you're camping on the tracks". (excl.) The word shouted when a train is headed for a known location (usually a zone border or guard station). e.g. "Train headed for zone!!!" cf. choo-choo.
