Hello, I'm Rdp060707. I noticed that you made a change to an article, Bombardier Innovia APM 100 C801, 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. Rdp060707&#124;talk 09:41, 22 July 2021 (UTC)

Please do not add or significantly change content without citing verifiable and reliable sources. Before making any potentially controversial edits, it is recommended that you discuss them first on the article's talk page. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Rdp060707&#124;talk 09:45, 22 July 2021 (UTC)

Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits – specifically this edit to Mitsubishi Heavy Industries Crystal Mover C810 – it appears that you had added original research, which is against Wikipedia's policies. Any facts, allegations, ideas or personal experiences you prepare to add to Wikipedia must be cited by reliable sources that we can also verify. Not only does original research refer to material such as the above for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. You can have a look at the tutorial by pressing here. Sorry for the inconvenience. Edgar Searle (talk) 01:59, 5 September 2021 (UTC)
