People travelling into and out of London until Monday should brace for 'unprecedented' travel disruption ahead of the Queen's funeral.
Hundreds of thousands, if not millions of people, are expected to descend on London over the coming days to pay their respects to the late Queen.
The sheer number of people in the Capital is expected to put a serious strain on the city's transport network.
In a bid to ease some of the pressure, commuters who can work from home have been urged to do so by the prime minister's spokesperson.
Ahead of the funeral on Monday, a ban on planes, kites and small balloons flying below 2,500 feet above certain parts of London has been enforced by the Civil Aviation Authority.
This is to ensure the safety and stop noise pollution above the Queen's coffin as it makes its way through London.
Some scheduled flights to and from Edinburgh airport are expected to be disrupted today.
Her Majesty will lie in state in Westminster Hall at the Palace of Westminster in central London from Wednesday until Monday morning.
During that time, hugely long queues stretching more than a mile are expected to build up along the River Thames.
While people have been warned not to wait or camp along the route where the Queen’s coffin will be taken in London, the queues and the crowds are likely to slow traffic down considerably.
Parts of central London will be closed to normal traffic, bus routes will be curtailed and some station access points may be closed.
When the Queen's funeral takes place at 11am on Monday, there will be extensive road closures, and some Underground and national rail stations could close.
Disruption on the rails is likely to not be as bad as it could've been after the RMT union called off its national strikes planned for 15 and 17 September.
There may be some additional issues on Thursday as crew schedules are redrawn, having been worked out with the strikes in mind.
Last night, rail bosses were drawing up plans for 24-hour train services into London ahead of the funeral, with capacity boosted by 50% on some lines.
Transport chiefs are expecting demand on railways and roads in the capital to be "unprecedented", Mail Online reports.
A special service of 12 trains per hour on the central section of the Elizabeth Line will come into operation, while Southeastern is set to run 24-hour services.
Announcements of which lines will be expanded are expected to be made on Wednesday.
The public have been told to avoid using Green Park station - which is close to Buckingham Palace - as high numbers of passengers are expected to pass through the stop.
Those looking to beat the transport rush by booking into a hotel may need to act quickly, as demand for rooms in the capital is rising.
The Rail Delivery Group (RDG), representing train operators, has said it is working to ensure people can get to London, and that those who decide not to to avoid the crowd don't miss out.
“We are working with our partners to review arrangements to get people to view the funeral where possible and where there is capacity," its spokesperson told The Independent.
"We have put in place changes that will ensure customers will not lose money if they change their plans or decide not to travel because of the death of Her Majesty the Queen."
People who have bought anytime, off-peak and super off-peak tickets can get refunds if they bought them before the death of the Queen can be refunded, with the £10 admin fee waived.
It was announced last week that the day of the funeral will officially be a bank holiday, meaning many of the people who would've been commuting into London will not be on the trains.
This may cause some issues at airports if employees request the day off to attend the funeral.
The government says it expects employers “to respond sensitively to requests from workers who wish to take the day of the funeral off work”.
