Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits to Kawasaki Heavy Industries & CSR Qingdao Sifang C151A, it appears that you have added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—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. Please be prepared to cite a reliable source for all of your contributions. You can have a look at the tutorial on citing sources.

Hello Omatcha. I have unfortunately had to revert your inclusion of two Youtube videos as a source as they are regarded as selfpublished sources and not appropriate for Wikipedia. Please read WP:YTREF where it details that "self-published media as seen on YouTube are often not acceptable sources". You may reply here if you have any further queries. Thank you!

Line delay
Hello Omatcha, thank you for assisting to change all the completion dates on the Jurong Region Line pages. However, there's an error in which you are referring to the line as the "JRL line", which would read as "Jurong Region Line line". Would you be able to amend the sentence across all the pages?

I suggest simple like "Initially expected to open in 2028, the restrictions on construction due to the COVID-19 pandemic has led to delays, with the completion date now in 2029." Seloloving (talk) 05:50, 26 March 2021 (UTC)


 * Hi, I will suggest the same as Seloloving, do also add in a source indicating the delay as well. Thanks --Justanothersgwikieditor (talk) 08:42, 24 May 2021 (UTC)

Hello, I'm Robertsky. I noticed that you added or changed content in an article, Cross Island MRT line, 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. Thank you. – robertsky (talk) 08:46, 24 May 2021 (UTC)

Removal of information, adding unsourced content, and feedback
Hello Omatcha. Several editors have tried to reach out to you on your editing, please respond on the talkpage if you can.

I recently reverted three mass edits of yours on the trainset pages. I would like to take the time to point out that Kawasaki Heavy Industries C151 is a Good Article by Wikipedia standards, which classifies certain articles according to their quality. Please do not erase so much content from an established article without engaging on the article talkpage. I could overlook the removal of content from the other two pages if you were rewriting them, especially since they lack proper sources, but your edit summary did not provide a reason. please use edit summaries when doing mass changes.

Your addition of content to the C151 page also listed several information with no sources: "The Land Transport Authority commenced the decommissioning of the KHI trains on 22 June 2020, starting with Train 045/046" and "Under contract R151D, the Land Transport Authority will hand over the remaining decommissioned trains to Toyotron Pte Ltd for dismantling, scrapping and disposal services". Would you have a reliable source for this? Again, take note sources from SGTrains, LandTransportGuru, forums, Youtube, or trainspotters seeing them on the roads cannot be used.

Another editor, Justanothersgwikieditor has also concurred with my advice about the "JRL line" and "CRL line" error. You recently added the same formatting error to the CRL and TEL pages - even copying the "CRL" name to the TEL station pages instead.

Being an editor on Wikipedia means you are required to communicate with other editors per Competence is required, criteria three. This does not imply you are incompetent, but communication is key to the project as noted. I note that you stopped adding unreliable sources such as Youtube after I wrote to you above, but do please do start to engage with us. We are all here to help. Thank you.

E5 and H5 Series Shinkansen‎
Hey, i've seen you merged the E5 Series Shinkansen and H5 Series Shinkansen articles into a new page, E5 and H5 Series Shinkansen‎. While i have no doubt that there is consensus to merge the two articles, wouldn't it have been better to merge the H5 series article into the E5 series article to preserve the page's edit history? Also, please don't forget to add the required attribution when copying material from one wikipedia article to another, per Copying within Wikipedia. Nyamo Kurosawa (talk) 20:34, 28 October 2021 (UTC)
 * Quick update: i've taken the liberty to close the merge discussion as "consensus to merge" and have merged the H5 Series page into E5 Series Shinkansen in order to have a complete and functioning revision history of the page. Also i have redirected the article you started, E5 and H5 Series Shinkansen, to E5 Series Shinkansen, as it duplicated the content of the page. If you have any questions, fell free to ask on my talk page. Best regards and happy editing! Nyamo Kurosawa (talk) 08:14, 29 October 2021 (UTC)

Hello, I'm KN2731. I noticed that you recently removed content from Punggol LRT line 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 your sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page.   ~ KN2731 {talk · contribs} 03:21, 6 November 2021 (UTC)

Hi, and thank you for your contributions to Wikipedia. It appears that you tried to give Toei 12-000 series a different title by copying its content and pasting either the same content, or an edited version of it, into Toei 12-000 and Toei 12-600 series. This is known as a "cut-and-paste move", and it is undesirable because it splits the page history, which is legally required for attribution. Instead, the software used by Wikipedia has a feature that allows pages to be moved to a new title together with their edit history.

In most cases for registered users, once your account is four days old and has ten edits, you should be able to move an article yourself using the "Move" tab at the top of the page (the tab may be hidden in a dropdown menu for you). This both preserves the page history intact and automatically creates a redirect from the old title to the new. If you cannot perform a particular page move yourself this way (e.g. because a page already exists at the target title), please follow the instructions at requested moves to have it moved by someone else. Also, if there are any other pages that you moved by copying and pasting, even if it was a long time ago, please list them at Requests for history merge. Thank you.

Speedy deletion nomination of New Rail Financing Framework
Hello Omatcha,

I wanted to let you know that I just tagged New Rail Financing Framework for deletion, because it seems to be copied from another source, probably infringing copyright.

If you feel that the article shouldn't be deleted and want more time to rewrite it in your own words, you can [//en.wikipedia.org/w/index.php?title=&action=edit&section=new&preload=Template:Hangon_preload&preloadtitle=This+page+should+not+be+speedy+deleted+because...+ contest this deletion], but don't remove the speedy deletion tag from the top.

You can leave a note on my talk page if you have questions. Thanks!

Proposed deletion of Mitsubishi Heavy Industries Crystal Mover C810D


The article Mitsubishi Heavy Industries Crystal Mover C810D has been proposed for deletion&#32;because of the following concern: "Another page already exists. You just copy-pasted this page to create it it."

While all constructive contributions to Wikipedia are appreciated, pages may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the page to address the issues raised. Removing will stop the proposed deletion process, but other deletion processes exist. In particular, the speedy deletion process can result in deletion without discussion, and articles for deletion allows discussion to reach consensus for deletion.

Cut-and-paste moves
You have received a number of notices regarding your cut-and-paste moves over the past year. Please stop making them as doing so is disruptive. If you want to move a page, please see this guide, or you can request a move. These options preserve the page history, which is legally required for attribution; cut-and-paste moves do not. If you continue to make cut-and-paste moves, sanctions may be imposed on you. Thank you. XtraJovial (talk • contribs) 12:38, 15 October 2022 (UTC)

Please do not use styles that are nonstandard, unusual, inappropriate or difficult to understand in articles, as you did in KiHa 85 series. There is a Manual of Style, and edits should not deliberately go against it without special reason. Please see MOS:DATEVAR; thank you. XtraJovial (talk • contribs) 13:51, 2 August 2023 (UTC)
