The "iPhone and suction cup" was tongue in cheek, but train drivers are already behind locked doors And anyone can already bring most trains to a stop by pulling the red "please stop this train" lever. Just install more cameras if you're worried, or get a security guard. Cheaper than a driver and takes less time to train (heh).
