Running late? Head for the middle coaches. They line up with exits at most stations, saving you a minute or two on the way out.

The 85-minute ride is just long enough to catch up on a podcast episode or reply to a few messages, but short enough that you won't miss your stop if you stay alert.

Travelling mid-day (11 AM-4 PM) or after 9 PM? You'll almost certainly get a seat, unlike the morning crush.

Don't pocket your token after entry. You'll need it again to tap out at the exit gates. Smart card users can just tap and go both ways.

At the interchange, just follow the overhead signs color-coded to the Blue Line (Line 1). The walk between platforms usually takes under 3 minutes.

First time on this route? The in-train display and audio announcements call out every upcoming station, so there's no guesswork involved.
