I don't like que jumpers. I don't like que jumpers who jump right next to me. And I definitely don't like que jumpers who do it in front of a bunch of people and then get in the way of everyone trying to get off the train.
So I've been trying to stop it. I'll share my strategies now:
1) This only works if you get to the door first.
Stand right in the middle in a wide stance. When the door opens turn sideways to let people off the train. Don't look at your phone.
This usually works. People can see your body language and follow your lead. Even a big group of people.
It's not perfect though.
2) when the door opens, put your arm in front of the queue jumper to stop them going inside. This has worked for me when there's lot of people wanting to get off the train.
3) with a friend, stand on the correct queuing arrows and hold hands across the out arrow. When the door opens, drop hands and turn sideways.
This is the best but you need a friend to do it.
Other ideas:
Use a walking stick.
Grab them by the scruff of the collar.
So far it seems to be older Chinese ladies.
