Tokyo Metro Ginza Line → Ginza lineGinza line – For Singapore MRT's lines, all of which have renamed from "xxx MRT line" to "xxx line" as the main article names. Does that case suitable for Tokyo Metro and Toei Subway series? Sinsyuan✍️TW→GA 03:15, 1 December 2025 (UTC) — Relisting. Jeffrey34555 (talk) 04:34, 8 December 2025 (UTC)[reply]

• A lot of similar RMs have been opened by the nominator at about the same time. It would probably have been better to open a multi-page RM. —⁠ ⁠BarrelProof (talk) 20:57, 1 December 2025 (UTC)[reply]

The result of the move request was: no consensus. After extended time for discussion, there is no consensus for the entire proposed move structure, but there is consensus to capitalize "Line" in each title. BD2412 T 03:40, 10 February 2026 (UTC)[reply]

– Most of these are restorations of articles to their titles prior to the recent page moves. The format of "Tokyo Metro X Line" appears to be the WP:COMMONNAME for each line. Additionally, some other line articles were not moved, creating an issue in regards to WP:CONSISTENT. Each page move received minimal participation so there does not appear to be a strong consensus on the new titles. The editor who proposed the previous moves appeared to express uncertainty with his proposals, and was extrapolating a titling format used to refer to a different system internationally (the Singapore MRT), which does not apply to the Tokyo subway. Additionally, the restoration of the diacritic to the Tōzai Line article title similarly meets WP:COMMONNAME and brings it in line with the other Tokyo subway article titles per WP:CONSISTENT.

• Comment All of these titles appear to be unambiguous. Why are you proposing to add unnecessary disambiguation? 162 etc. (talk) 17:15, 2 January 2026 (UTC)[reply]

Comment I don't have an opinion on this at the moment (other than those I opposed previously), but all the lines which were moved to the smallcase L in "line" should have the L moved to uppercase, per MOS:PROPERNAME and WP:CONSISTENT with other Japanese railway lines. S5A-0043🚎^(Talk) 09:36, 3 January 2026 (UTC)[reply]

Support moving them back to a consistent format. Per S5A-0043, we should at least uppercase the word "line" per MOS:PROPERNAME and to be WP:CONSISTENT with Japanese rail lines. – Epicgenius (talk) 18:01, 4 January 2026 (UTC)[reply]

Maybe the title name could be controversial for WP:COMMONNAME and WP:DISTINGUISH. Japanese Wikipedia has the guidelines for naming the railway lines (ja:Wikipedia:記事名の付け方/鉄道#日本の路線). For that case, the Tokyo Metro lines in enwiki is forced to be titled "Tokyo Metro xxxx Line". However, the English Wikipedia doesn't have the similar naming guidline like Japanese Wikipedia say. Sinsyuan✍️TW→GA 04:48, 6 January 2026 (UTC)[reply]

Also, for distinguishing, there's no second line named "Ginza", "Marunouchi", "Hibiya", "Hanzōmon", "Fukutoshin", "Chiyoda", "Asakusa", or "Ōedo". If these articles remamed back to "Tokyo Metro xxxx Line" or "Toei xxxx Line", it could be lengthy and redundant (named after the operator name). For evidence, "Midōsuji Line", "Tanimachi Line" (Osaka Metro). Sinsyuan✍️TW→GA 08:50, 6 January 2026 (UTC)[reply]

In that case, these could be moved to Ginza Line, Marunouchi Line, etc. (or if disambiguation is necessary, Tōzai Line (Tokyo Metro)); the article titles for each of these are proper nouns and still should be capitalized. However, WP:CONSISTENT is being violated here, since we have a mixture of capitalizations and disambiguation customs here. – Epicgenius (talk) 14:24, 6 January 2026 (UTC)[reply]

Hmm...I suggest remaining the present title like Wenhu line, Island line (MTR) (for WP:LOWERCASE). Sinsyuan✍️TW→GA 09:41, 7 January 2026 (UTC)[reply]

After looking at other Japanese railway line article titles, I'm fine with compromising with Epicgenius' suggestion to at the very least excluding the operator name wherever it is unnecessary and using a WP:CONSISTENT disambiguation custom wherever it is. However, I oppose retaining the lowercase "line" in the article titles per S5A-0043. "Line" appears to be part of the proper name for each of these lines. WP:LOWERCASE does not apply to proper names; MOS:PROPERNAME does, which stipulates that "Line" should be capitalized here. OrdinaryScarlett (talk) 23:42, 7 January 2026 (UTC)[reply]

1. For Taipei Metro, "Wenhu line", etc.
2. For Taiwan Railway, "Western Trunk line", etc.
3. For Tokyo Metro, "Ginza Line", etc.
4. For JR, "Yamanote Line", etc.
5. For Beijing Subway, "Batong line", etc.
6. For NYCS, "Flushing Line", etc.
7. For London Underground, "Victoria line", etc.
8. For MTR, "East Rail line", etc.
9. For SMRT, "Thomson–East Coast Line", etc.

I think the title for subway(metro)/railway lines should be consensus for "xxx Line" or "xxx line" (controversial between WP:CONSISTENT, MOS:PROPERNAME, and WP:LOWERCASE). Sinsyuan✍️TW→GA 12:58, 8 January 2026 (UTC)[reply]

WP:CONSISTENT applies to similar topic areas; i.e. lines within a certain transit system. So, consistency in naming applies to lines within the same transit system, not globally. Different systems worldwide depend on a case-by-case basis; some treat "Line" as part of the proper name, others don't. So, enwiki utilizing different capitalizations for "Line" vs. "line" across different systems worldwide is normal, not an inconsistency. Again, if "Line" is part of the proper name of a line, then MOS:PROPERNAME stipulates that "Line" should be capitalized. If not, then WP:NCCAPS stipulates that "line" should not be capitalized.

If you feel strongly about discussing the cases of other systems, you're free to on the appropriate talk pages, but it is beyond the scope of this discussion. OrdinaryScarlett (talk) 22:36, 8 January 2026 (UTC)[reply]

WP:EN English-language sources trump Japanese sources when determining the name of an English article. I'd be surprised if there aren't enough English-language sources that we have to rely on non-English sources for these. Erynamrod (talk) 19:46, 9 January 2026 (UTC)[reply]

Oppose addition of opperator name, but support capitalization of "Line". The majority of English-language sources I'm finding simply refer to the lines as "Ginza Line" for example, though some do introduce it as the "Tokyo Metro Ginza Line" or even "Tokyo Metro's Ginza Line" once then call it simply the Ginza Line after.[5][6][7][8][9] — Preceding unsigned comment added by Erynamrod (talk • contribs) 12:02, 10 January 2026 (UTC)[reply]

Per Erynamrod, I'd like to rename the Tokyo Metro Lines series to "XXX Line" (excluding Namboku and Tozai). Although many comments would like to set the name of "Tokyo Metro XXX Line", in fact, there aren't any other lines with the same name (for Chiyoda, Ginza, etc.) Sinsyuan✍️TW→GA 01:57, 17 January 2026 (UTC)[reply]

Oppose "Tokyo Metro XYZ Line", Support "XYZ Line" (with L capitalized) - Most Wikipedia articles about train lines around the world don't have their operator mentioned (see OrdinaryScarlett's reply). So, instead of adding Tokyo Metro, make it just the line name with "Line" with an uppercase L to make it more consistent. All the lines inside Tokyo seems to have it capitalized as well. EvanTech10 (talk) 23:54, 25 January 2026 (UTC)[reply]

If there is consensus for renaming, please consider renaming article titles for other means of railway lines operated by Tokyu, Toei, Tobu, Seibu, Odakyu, Keikyu, Keisei, Keio, Sotetsu, etc. Sinsyuan✍️TW→GA 09:36, 31 January 2026 (UTC)[reply]
