In October, Ward wrote to say that the stories would be published as one book entitled " The Three Railway Engines", but that he required rough sketches for his illustrator to base his pictures on and a fourth story to finish off the book. Her attempts to find a publisher were initially no more successful, as most were suffering paper shortages due to the Second World War, but in September 1943, Edmund Ward agreed to publish them, though refused to commit to a publication date, to Wilbert's annoyance. Barsley's attempts to find a publisher were unsuccessful, so he showed the stories to his agent, Edith Ray Gregorson, who liked them and agreed to pursue the matter further. At Margaret's insistence, Wilbert did so.
Awdry was reluctant, but Margaret persisted and mentioned the stories in a letter to Wilbert's mother, Lucy, who replied that she knew the author Michael Barsley and asked that the stories be sent to her so she could forward them to him.
Margaret Awdry also liked the stories and told her husband to get them published, as she felt they were better than most children's books in circulation. Christopher would constantly ask for the stories to be retold, even after he recovered and to ensure consistency between tellings, Wilbert wrote them down on the back of old church circulars. Eventually, Christopher began asking for more stories and Awdry obliged him with "Edward and Gordon" and "The Sad Story of Henry", the latter being inspired by another rhyme he was fond of. Through a series of questions and answers, the story of Edward's Day Out was created. Wilbert replied with the first to come to his head: Edward. One sad-looking engine appealed to Christopher, as it shared his mood and he asked what his name was. Wilbert subsequently drew a picture of several engines standing in a row based on the rhyme and for fun gave them faces with various expressions. Most of them eventually lost their entertainment value, but one that continually appealed to Christopher was the rhyme " Down by the Station".
To prevent their son getting bored, Wilbert and his wife Margaret Awdry told him stories and nursery rhymes. The algorithm created in this way solves the problem of detection of relevant signals along the train route, especially in multitrack scenarios such as stations and yards.In 1942, Wilbert Awdry's son Christopher had measles and was confined to bed. Calculated values of average precision and recall were 0.89 and 0.76, respectively. The obtained value of IoU applied on the entire validation dataset exceeds 0.7. The metric method used for validation was intersection over union (IoU). The reliability of the proposed algorithm in detection of a relevant signal, verified by the performed tests, is up to 99.7%. This approach ensures that the artificial intelligence (AI) system is “aware” of which route the signal belongs to. Each of the concepts (CV and CNNs) deals with a different object of detection which together form a unique system that aims to detect both the rails and the relevant signals. The algorithm integrates traditional computer vision (CV) algorithms, including Canny edge detection, Hough transform, and You Only Look Once (YOLO) algorithm, based on convolutional neural networks (CNNs). An algorithm for the detection of railway infrastructure objects, namely, track and signals, is proposed in this paper to enable detection of signals which are relevant for the track the train is moving along. An important segment of self-driving is the ability of the computer to “see/detect” objects of interest at a distance which enables safe vehicle operation. One of the most challenging technical implementations of today is self-driving vehicles.
