Queen Elizabeth II: Here's how people travelling from West Sussex can travel to London by train for the lying in state and Her Majesty's funeral.

Her Majesty will lie in state in Westminster Hall at the Palace of Westminster in Central London between Wednesday September 14 and Monday, September 19 with queues expected to be lengthy.​

The funeral will then take place at 11am on Monday, September 19.

In a statement on their website National Rail said: “Many people from across the country will wish to travel in the coming days to pay their respects to Her Majesty the Queen and the rail industry is working hard to enable people to do that. "However, we would urge people to check service details before travelling and to be prepared for very busy trains and stations.”Some Tube stations in the area may be closed during the Funeral.

A number of roads may be closed at short notice while the coffin is moved through Central London, with bus routes altered and Tube stations closed, to prevent overcrowding.

There may be a large number of people travelling to and within London for Her Majesty’s funeral.

All major London train stations will have extra staff around to help passengers on their journey.

You can plan your journey using the Transport for London and National Rail Enquiries websites. You can find up-to-date travel information by following National Rail Enquiries on Twitter or downloading the TfL Go app.

For those travelling into London, the main National Rail stations are: Blackfriars, Cannon Street, Charing Cross, Euston, King’s Cross, Liverpool Street, London Bridge, Marylebone, Paddington ,London St Pancras, Victoria ,Waterloo and Waterloo East.

On the day of the funeral, off-peak restrictions will not apply and off-peak tickets can be used throughout the day and passengers should check before travel on the day as London and Windsor are expected to be very busy.

Transport bosses have also confirmed that extra train services will be running for people travelling to London to pay respects to the Queen.

A limited service will run through the night on some routes.

Demand is expected to be particularly heavy from Wednesday, when the public can attend the lying-in-state at Westminster Hall from 17:00 BST.

The Rail Delivery Group said it was doing "all it can" to ensure smooth journeys during the period of mourning.

In a official statement by the UK Government, it reiterated the need for passengers to check before they travel.

The statement said: “Her Majesty The Queen’s Lying-in-State at the Palace of Westminster opens to the public at 5pm on Wednesday, 14 September. It will be open 24 hours a day until it closes at 6.30am on Monday, 19 September.

“If you wish to attend the Lying-in-State, please note that there will be a queue, which is expected to be very long. You will need to stand for many hours, possibly overnight, with very little opportunity to sit down as the queue will be continuously moving.

The queue for the Lying-In-State will start where Albert Embankment meets Lambeth Bridge in Central London, on the south side of the River Thames. From Albert Embankment, the queue will continue along the south bank of the Thames.

The statement continued, saying: “To visit the Lying-in-State, you need to join the back of the queue. The location of the back of the queue will move depending on how many people are queuing.

“When you reach the back of the queue, you will be given a coloured and numbered wristband. This is a record of when you joined the queue, however please note that having a wristband does not guarantee your entry to the Lying-in-State.

“Wristbands are specific to each person joining the queue, and are strictly non-transferable. You must keep this wristband on at all times as it will be checked along the route.

“Your wristband also allows you to leave the queue for a short period to use a toilet or get refreshments, then return to your place in the queue. Public toilets, drinking water and first aid stations are available at designated locations along the queue route.

“Before entering the Palace of Westminster, everyone will be subject to an airport-style security search. There are restrictions on what you can take in and bag sizes.

“If you have a large bag that you are not permitted to take into the Palace of Westminster, stewards will direct you to the bag drop facility before you enter the security search point. You will not lose your place in the queue, but it may increase your queuing time.

“Step-free routes and an accessible queueing scheme are available for those who need them.

“When you leave the Palace of Westminster, you will exit onto Parliament Square. If you left a bag or other item at the bag drop facility, you must collect your item straight after your visit.

“Follow the signs and directions given by stewards to return to the bag drop facility and collect your bag or item.

“You will be asked to remove your wristband when you exit. If you are collecting items from the bag drop, keep your wristband with you as you will need it to collect your item.

“You should move away from the exit straight away so that you do not prevent others from exiting. This will help everyone to keep the queue moving and mean as many people as possible are able to visit the Lying-in-State. Stewards can direct you to nearby public transport stations.”
