The Queen, the Duke of Edinburgh and the Duchess of Cambridge are going underground, to celebrate the 150th birthday of the tube.
The Royal party will be greeted at Baker Street by the Commissioner of Transport for London, Sir Peter Hendy, and the Managing Director of London Underground Mike Brown.
They'll meet maintenance and train staff and will view a restored 1892 underground coach. They'll then walk through a new S7 train where the queen will unveil a plaque, naming the train Queen Elizabeth II.
An old version of London Underground's iconic 'Mind the Gap' announcement is to be restored at Embankment Tube station, after the widow of the actor who recorded it asked for the chance to hear her husband's voice again.
Oswald Laurence made the recording more than 40 years ago and could be heard all over the capital until it was phased out.
Embankment eventually became the only station to play the message, with Mr Laurence's widow telling staff she used to go there after his death so she could listen to his voice until it was eventually discontinued there too.
London Underground director Nigel Holness said: "Transport for London were approached by the widow of Oswald Laurence to see whether she could get a copy of the iconic 'mind the gap' announcement her husband made over 40 years ago.
"We were very touched by her story, so staff tracked down the recording and not only were they able to get a copy of the announcement on CD for her to keep but are also working to restore the announcement at Embankment station."

Judge: runaway wagon had potential for 'terrible tragedy'
London Underground, Tube Lines Ltd and Schweerbau GMBH had pleaded guilty to endangering passengers and staff under Health and Safety law, after the 39-tonne maintenance wagon hurtled through seven stations before it could be stopped.
A train in front of it was told to keep going and not stop, while its passengers were told to run to the front carriages, the Old Bailey heard.
Judge Richard Hone said: "There was the potential of terrible tragedy."
He said the runaway train was out of control for four miles during 16 minutes.
"To those involved it must have seemed an extremely frightening eternity," he added.
