Getting squashed by train doors isn’t as easy as it looks.
First, get onto a platform where a train is just about to depart.
Next, upon getting on the platform, double-check that you’re getting the right train. This may take a while if your stop hasn’t appeared on the scrolling list yet. If you’re with friends the next step will be easy.
Ask your friends whether or not to get on the train. If they say yes, make sure you’re the last one to get on. Let them hurry through the door yet casually make their way inside the train while you listen to the automated man saying ‘Stand clear, doors closing’ followed by numerous beeps telling you to move away.
This is where the fun begins.
When you hear the first beep, you must be half a metre away from the floor because of your friends strolling their way deeper into the carriage as they pass the door. The third beep is when you make your move and find yourself stuck between two closing doors.
Thankfully I got through with minor shoulder/hip/toe pains.
To my friends who caused this incident, bfflnmw. :p
