Princess Anne received a special "honour" during her visit to Paddington station on Thursday.
The Princess Royal had a train named after her in recognition of her support for more than 300 charities and military regiments in the UK and overseas.
Anne traveled to Paddington train station with her husband Vice Admiral Sir Tim Laurence who is a member of the Great Western Railway Board.
The 73-year-old royal looked smart in a grey blazer with a matching maxi skirt and a pair of knee-high leather boots.

She accessorised her outfit with a pair of black gloves and a bright green shirt decorated with a bow.
The princess made a speech during the event stating: "Thank you very much indeed for this honour, it's much appreciated.
"But I hope you that you recognise the common denominator here is the understanding of the word logistics, in this case particularly railways.
"I do think that's a subject which many of the organisations that I'm involved with really do have a clear understanding of, it is their role."

Anne unveiled a curtain to show the new Intercity Express Train with the writing "HRH The Princess Royal" on the side to the crowd's applause.
The princess continued: "I'm grateful for their persistence in understanding that particular area of work and for which we understand the railways, the key part they play, for everybody and that it has a real future.
"This is really kind of you but does it reflect, I hope, a real understanding of the role of logistics, particularly railways, in our lives, certainly historically but definitely for the future."
Above Anne's name are prints of two sides of a coin; one showing an illustration of the princess competing at the 1976 Montreal Olympics and the other with the Coat of Arms of the GWR.
