Prompt
"Generate an image of a railway line stretching through the English countryside, with a train operated by Chiltern Railways traveling along the tracks. The line should be depicted in a rural setting with rolling hills and fields, and should include notable stations such as London Marylebone, Harrow-on-the-Hill, Amersham, Great Missenden, Wendover, Stoke Mandeville, and Aylesbury. Incorporate subtle hints of the line's history, such as vintage signs or old railway infrastructure, to reflect its operation since 1899. The style should be a realistic representation of a railway line in England, with muted colors and a focus on capturing the essence of the London to Aylesbury Line."
