> PS, why do people stick their necks over the tracks to look if a train is coming?
You can often see further down the tunnel from an angle close to the tracks than you can standing behind the yellow strip. If someone ahead of you on the platform is already doing this, then they're probably blocking your view down the tunnel, so you have to lean to see past them. It seems pretty silly, but sometimes it's useful, for example, in determining whether the express or local will come first, and you can then switch platforms at the last minute if it makes sense for you.
If countdown timers were reliable and accurate, fewer people would feel compelled to lean out.
