Prompt
"Generate an image of a Chiltern Railways train at London Marylebone station, with the iconic Chiltern Railways logo visible on the train. The train should be a Class 165, 168, 172 or 68 unit, and should be surrounded by typical British railway infrastructure. In the background, include a blurred image of the London Marylebone station building. The style should be realistic and evocative of a typical British commuter rail service. The image should convey a sense of movement and activity, with the train ready to depart for destinations such as Birmingham Moor Street, Aylesbury, Oxford, Banbury or Stratford-upon-Avon."
