Great Western Railway will name one of its new Inercity Express Trains after Nancy Astor today - the first female MP in the House of Commons.
The train will be unveiled exactly 100 years after she joined parliament, representing the Plymouth Sutton constituency.
Passing through Reading, the train's inaugural voyage from London to Plymouth will then retrace Lady Astor's visits - including her country retreat at Cliveden near Maidenhead.
Leader of the Nancy Astor Statue Campaign, Alexis Bowater said:
"We are so proud that Great Western Railway has been working with us and supporting this celebration of democracy and recognising Nancy Astor.
“It is a wonderful legacy to leave."
Great Western Railway claims the new Inercity Express Trains will offer customers more space, comfort, and faster journeys.
The naming ceremony will take place at Paddington Station, a century since the by-election result in the seat previously held by her husband.
VIPs, including members of the Astor family, will join the celebrations onboard before a bronze statue of Lady Astor is unveiled on Plymouth Hoe.
Dr Jacqui Turner, historical advisor to the campaign from the University of Reading, leading the Astor 100 programme, said:
“The election of Nancy Astor changed British democracy forever.
"For the first time, a woman was able to directly influence the parliamentary debate and the writing of the laws of her own land.
“Today, she continues to make history and we hope the train renaming, statue unveiling and other activities involved in the Astor 100 project will inspire further changes in politics."
