Hi Danners 430. I am concerned that you reverted my edit re pressure gauges in the carriages of these underground trains. I cannot find any direct citation to them from the manufacturer (Bombardier), but I can assure you that they exist on every coach. As a professional engineer it is evident that the guage readings are directly proportional to the brake pressure applied to the wheels in real time. I have a photograph of the gauge in situe, but I do not have a direct citation from the manufacturer. I can vouch for it being the truth though. Can I ask you to reinstate this truth in the hope that others or yourself might help in finding a third party citation for it. — Preceding unsigned comment added by Canol (talk • contribs) 17:53, 15 February 2025 (UTC)[reply]
Hi Canol, I too am a professional engineer, and have no reason to doubt the accuracy of the statement made. However, Wikipedia is an encyclopaedia - it is a collection of verifiable facts. Please take a look at WP:TRUTH. Danners430 (talk) 18:28, 15 February 2025 (UTC)[reply]
Yes, I’ve read that and it’s covered by stating (citation needed) it’s mentioned towards the end of WP:TRUTH. Will you reinstate please, the statement is true, improves the page, complies with WP:TRUTH and enlists the help of others to provide a citation.

(talk page watcher) @Canol: Also, you inserted your unsourced text immediately prior to a reference that does not support what you added. Now, I have seen such gauges in Underground train cars - they're usually to be found in the protective panelling of under-seat equipment - but (unlike, say, a speedometer) the gauge does not convey any information to those who observe the needle move but do not know its purpose. --Redrose64 🌹 (talk) 19:44, 15 February 2025 (UTC)[reply]
I am talking about the brake pressure gauges on the carriage wall of all type S7 and S8 stock, not the older type carriages where gauges were mounted below seats.I would hope to reinstate this with a note asking for citations. There are a number of unfounded statements in this article where there is no citation, at least I can vouch for the validity of mine. The truth stands scrutiny cited or not.

I’ve read WP:TRUTH and it stated towards the end that it is acceptable to state “citation needed” after the post. Indeed Wikipedia is peppered with “citation needed” as it complies with Wiki rules. Canol (talk) 22:21, 15 February 2025 (UTC)[reply]
I've read WP:TRUTH too. I can't find what you claim. Exactly which paragraph does it appear in? You may provide the first four or five words of the paragraph, so that we may also find it. --Redrose64 🌹 (talk) 22:50, 15 February 2025 (UTC)[reply]
Just type “Citation needed” on Wikipedia search. I’ve given this enough time so if you don’t want to reinstate a truthful statement who’s author is looking for help in getting a citation so be it. Goodnight. Canol (talk) 23:40, 15 February 2025 (UTC)[reply]
At WP:TRUTH, the word "citation" occurs exactly once, in the bullet point beginning "Verifiability: In Wikipedia's sense, material is verifiable ..."; and the word "needed" occurs just twice, the first time in the paragraph beginning "In many cases, if something appears in a reliable source ..." and the second in the paragraph beginning "By "natural science" is here meant a science such as geology ...". At no point do the two words occur together. --Redrose64 🌹 (talk) 00:17, 16 February 2025 (UTC)[reply]
