The initiative involves transporting wreaths on early morning trains to Paddington station for a dedicated service.
While at Chippenham Railway Station, Queen Camilla was presented with a crocheted poppy wreath by 10-year-old Eira Jones, which she took with her to London.
Upon arrival, Camilla placed a wreath of poppies at the war memorial on Platform One, followed by the Last Post and a two-minute silence.
