Scenario a): No international transport for up to 24 hours.
Scenario b): No domestic rail or air transport and severe delays to road transport for up to 24 hours with gradual restoration of normal service over a period of 4 days.
Scenario c): Significant disruption to local transport networks for up to seven days.
Scenario a) This scenario would involve closure of UK airspace and some maritime borders for a 24 hour period prohibiting inward or outward movements as part of the response to a major incident(s).
Scenario b) This scenario may arise under extreme weather conditions and heavy snow, disruption to fuel distribution or the electricity planning assumption (see section 4). Industrial action by transport staff could also cause disruption, but this would probably be shorter in duration.
Scenarios c) This scenario could be caused by a number of situations. As there are generally alternative modes of transport available, severe delays rather than complete denial are likely.
