Hello, I'm Materialscientist. I noticed that you made a change to an article, ALCO S-6, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Materialscientist (talk) 23:46, 21 January 2023 (UTC)

Please do not add or change content, as you did at ALCO FA, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you. Trainsandotherthings (talk) 23:50, 21 January 2023 (UTC)

Please stop. If you continue to add unsourced or poorly sourced content, as you did at ALCO RS-11, you may be blocked from editing. Trainsandotherthings (talk) 23:55, 21 January 2023 (UTC)
