A delayed train turns a simple pickup or boarding into a waiting game — especially when you don't know the platform or how much longer it'll actually be.
Why platform numbers change, especially when trains are late
Platform assignments aren't always fixed in advance, particularly at larger junctions, and a delayed train is more likely to get reassigned to whatever platform is free when it actually arrives. That's why the platform shown well in advance isn't always the one the train ends up using.
When to check, and when to check again
Checking once when you leave home isn't enough if the train is significantly delayed — platform and arrival estimates get more accurate the closer the train gets to your station. It's worth a second check as you're arriving at the station, not just before you leave.
Reading "expected arrival" correctly
Expected arrival times are estimates based on the train's current speed and location, not guarantees — treat them as a reasonable window rather than an exact minute, especially for trains running well behind schedule.
