Hello, I'm Hydrogenation. I noticed that you recently removed content without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.

Hello, I'm Hydrogenation. I noticed that you added or changed content in an article, GNR Class A1 1470 Great Northern, 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 the tutorial on citing sources. If you think I made a mistake, you can leave me a message on my talk page.   Hydrogenation (talk) 17:19, 24 June 2021 (UTC)
