More overnight trains have been arranged as the day of Her Majesty’s State Funeral approaches.
Avanti West Coast has also added four daytime services from Manchester to London using locomotives and rolling stock hired from a charter company.
Southeastern has said it will be running night services on main line routes, and has declassified First Class until Tuesday.
Network Rail chair Sir Peter Hendy said: ‘The transport industry is working hard to help people pay their respects in London and across the United Kingdom.’
The focus of Monday will naturally be on London and Windsor, amd London transport commissioner Andy Byford has said Transport for London faces a bigger challenge than it did during the Olympics in 2012.
He also said it was an ‘important and difficult time for the country’. He continued: ‘We are doing everything we can to ensure Londoners and visitors can pay their respects to Her Majesty The Queen and welcome His Majesty the King. We are working with our partners to keep our city moving smoothly and to ensure that everyone who needs to get around or is planning to attend the memorial events can do so safely. I would urge all customers to check before they travel, using the TfL website or TfL Go app, as while we’re planning to run a normal service, there may be short notice changes and diversions as a result of the large number of people travelling and necessary road closures.’
In particular, passengers are being asked to consider walking the final stages of their journeys in central London, and to avoid Green Park Underground station if possible.
