We could make our railway more resilient to such attacks, but in general why bother ? It is probably cheaper to pay the cost whenever the disruption happens. At least in times of peace. There are two issues here though. The first is that the Olympics is a special event and it is more likely for somebody to try to cause the disruptions, and as such more control is probably warranted. The second is that somebody else (Russia) is not acting like they are at peace with us so we should act accordingly
