Hello, I'm Maurice Oly. I noticed that you added or changed content in an article, British Rail Class 317, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Maurice Oly (talk) 23:04, 20 December 2021 (UTC)
