Are there many case scenarios of what could happen to a runaway train?
Probably not. The most desirable outcome would be for a hiatus that causes minimal damage.
To achieve this, one would need to refer to the place where the train is being driven from.
Is the driver unhinged? If so, how can he or she be coaxed into ‘taking a break’?
It is only when this done that anyone else can apply brakes.
