Following the sad passing of Queen Elizabeth II, many mourners are expected to visit the capital to pay their respects to the late monarch.
Roads and public transport services are expected to be incredibly busy over the next week, especially on Monday, September 19 as the Queen's state funeral will take place in Westminster Abbey.
With concerns of very busy services, Transport bosses have 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, whilst others will have early trains in the morning.
Demands are expected to be particularly heavy from Wednesday when the public is invited to the Queen's lying-in-state at Westminster Hall from 5pm.
Mourners pay tribute to Queen Elizabeth II
Westminster Hall will be open for 24 hours for four days to the public until the day of Her Majesty's funeral on September 19.
The Rail Delivery Group has said that it is doing "all it can" to ensure smooth journeys during the time of mourning.
The group also said that customers travelling during the busier time should check journey planners for the most up-to-date information.
It comes as some expect millions to travel into the capital over the next week, seeing stations and services and in London be "extremely busy" as a result.
Many train companies are encouraging passengers to leave plenty of time to travel during the period of mourning.
Sir Peter Hendy CBE, chair of Network Rail said: “The transport industry is working hard to help people pay their respects in London and across the United Kingdom.
"Please make sure you check before you travel as we expect the road and transport networks to be busy."
