Stopping a train in the tube between stations is not safe. You can't get off the train safely between stations. Most help can't reach a train stuck in a tube.

Trains can be, and sometimes are, evacuated in a tunnel. The front (and rear, these trains are symmetrical) can be opened, converting into steps for able-bodied passengers to walk down to the tunnel floor.

There's a video of passengers doing this for real in this 2016 news article:

Note the electrified third rail in the photos. It's not safe to walk there before that rail is disconnected.
