Discussion regarding the Line Colours

[edit]

As per the articles on the lines, the colour schemes are-

  • Line 1 - NAVY
  • Line 2 - RED
  • Line 3 - YELLOW
  • Line 4 - ORANGE
  • Line 5 - PINK
  • Line 6 - GREEN

Recently I came across this official map (https://mtp.indianrailways.gov.in/uploads/files/1504000368490-System%20Map%20of%20Metro%20Railway_31_03_2017.jpg), where the colour scheme is different.

  • Line 1 - NAVY
  • Line 2 - GREEN
  • Line 3 - VIOLET
  • Line 4 - RED
  • Line 5 - Pink
  • Line 6 - ORANGE

Since till now, no colour coding system exits, we can either keep the current one, or update according to the official map. I have put this here, so that the editors can have a discussion. Saha ( talk ) 07:04, 19 June 2019 (UTC)[reply]

Confused

[edit]

@ArnabSaha:Could you tell me why you removed my diagram？If there are any errors in this diagram, please tell me. Thanks. -Painjet (talk) 16:19, 22 March 2020 (UTC)[reply]

Painjet, hi
1) the map was incorrect. some stations aren't operational, but was included
2) operational map was given in the evolution of kolkata metro map. ❯❯❯ S A H A 17:32, 22 March 2020 (UTC)[reply]
@ArnabSaha:Ok, I got it, thanks. The evolution of kolkata metro map is a gif file. I do not think it is intuitive for readers. Obviously, the svg or png is more suitable.-Painjet (talk) 06:41, 23 March 2020 (UTC)[reply]
Painjet, remove dakshineshwar, baranagar and phoolbagan from the map. also remove the heading. ❯❯❯ S A H A 07:54, 23 March 2020 (UTC)[reply]

It is certainly better to show operational map in the infobox, not the map with uc/planned lines. Jklamo (talk) 08:38, 23 March 2020 (UTC)[reply]

Possible suggestions

[edit]

Here is a list of suggestions I have for this page.

  • Expand the lead section (the very top) a bit, to 3 paragraphs at the very least. Possibly have the second paragraph talk about history and the third paragraph talk about operations, fares, etc. But don't make it too long.  Done
  • Per WP:CITELEAD, citations aren't really needed in the lead section if they are also used elsewhere.  Done
  • In "History", clarify what independence is. Indian independence?  Done
  • Use {{convert}} to convert km to miles where applicable.  Done
  • Avoid using terms like "crore" per MOS:CRORE, unless you link them or provide a clarification.  Done
  • By 2011-12, the Railway Ministry announced plans for the construction of five new metro lines and an extension of the existing North-South corridor. - what is the status of this?  Done
  • For the "Network" section, should it be part of the "Lines" section? Also, these tables need more sources, particularly for track gauge and length.  Done

More later. epicgenius (talk) 17:56, 27 May 2020 (UTC)[reply]

Epicgenius,
  • the lines mentioned in the 6th point (2011-12) are the same 5 lines mentioned in the network. (line 2, 3, 4, 5, 6)
  • the 7th point 'network section', is similar to Delhi Metro. In that article also, network and lines are different. and I also think it is better, otherwise, further sub-headings will be required for the line names, which won't look good...
  • now regarding the WP:CITELEAD, the citations aren't used elsewhere, so better keep them. ❯❯❯ S A H A 14:56, 28 May 2020 (UTC)[reply]
Alright, I will respond to these one by one.
  • the lines mentioned in the 6th point (2011-12) are the same 5 lines mentioned in the network. (line 2, 3, 4, 5, 6) - in this case, you can have a link to the section below, in "network".  Done
  • I see your point about keeping "network" separate.
  • the citations aren't used elsewhere, so better keep them - preferably, the citations should be used somewhere else in the article.
Also:
  • Sentences like It has a combination of elevated, ground-level and underground lines - in these cases, you might mean "tracks".  Done
  • Use {{TrackGauge}} for track gauges. E.g. instead of {{convert|1676|mm}}, use {{TrackGauge|1676mm}}.  Done
  • Relatively minor information, such as signal upgrades and the stations in metro extensions, should usually be moved to the respective articles about the lines.
  • Kolkata Metro is the busiest metro system in India based on passengers carried per service. Each service carries an average of 2,465 people, while Delhi carries 1,111. - this isn't usually a metric used to measure ridership.
  • Platform lengths, and the fact that certain stations have island or side platforms, are usually not important and can be removed.
More later. epicgenius (talk) 15:04, 28 May 2020 (UTC)[reply]
Epicgenius,
  • this isn't usually a metric used to measure ridership - ya. i know. but, on the basis of per km or per service, it tops. so I mentioned.
  • this case, you can have a link to the section below, in "network" - linked them.
  • preferably, the citations should be used somewhere else in the article - removed all except one. couldn't shift it anywhere.
  • signal upgrades - keeping this, since it is the only system in India to have this. ❯❯❯ S A H A 18:08, 30 May 2020 (UTC)[reply]
OK, here are more comments.
  • Further expansions - can you note which ones are now underway, which ones have been confirmed, and which have not been confirmed/are canceled, if any?
  • 55 – 60 km/h - use the {{convert}} template  Done
  • Navigation information is available on Google Maps. - is this noteworthy? Seems to be quite common.
  • Are "Tokens" and "Smart Card" supposed to be subsections of "Fares"? {{done}
  • Durga Puja special services - can you summarize what Durga Puja is, in a single sentence? What is pandal-hopping?  Done
  • What is lac? Seems to fall under WP:CRORE  Done
  • The newly inaugurated Line 2 - as of when?
  • Since the electrification of Kolkata metro is of the 3rd Rail - "since the Kolkata metro uses third-rail electrification". There are more minor grammar errors like these, but I think a copy-editor will pick them up.
These are my final comments so far. epicgenius (talk) 19:13, 3 June 2020 (UTC)[reply]
Epicgenius,
  • Further expansions- no progress regarding that. those are surveyed and planned since the existing lines aren't complete yet, the govt decided not to sanction any new.
  • Navigation information is available on Google Maps- in India, the feature is new. also for other modes of transport. and found this in the Delhi metro too.
  • The newly inaugurated Line 2- 13 Feb, 2020. just after a month, lockdown happened, and that's why very less ridership. and it's too low w.r.t. to Line 1, so mentioned "new" ❯❯❯ S A H A 19:23, 3 June 2020 (UTC)[reply]

Prose

[edit]
  • There are a total of 358 services everyday - "every day" in this case as "everyday" is an adverb

  • An east–west metro railway connection, named the "East–West Tube Railway", was proposed for Kolkata in 1921 by Harley Dalrymple-Hay, but it was ultimately not undertaken due to a lack of funds in 1923. - I'd move the "in 1923" part earlier. I'd suggest "it was cancelled in 1923" or something similar. Also, this needs a source.
  • 'Shield Tunneling' & 'Cut & Cover' - these should be lowercase, and the "&" should be "and".
  • Despite this, services began on 24 October 1984 - I wonder whether this should be a new paragraph.
  • by bridging the 1.80 km (1.12 mi) gap in the middle - a gap between which stations?
  • had 50–50 shares in it - I'd suggest "each had a half-share". It's not clear that this is a percent
  • Major modifications: I'd suggest making these paragraphs instead of bullet points.

Epicgenius, done ❯❯❯   S A H A 18:51, 17 July 2020 (UTC)[reply]
  • Should the Kolkata Metro route map be collapsed by default? Generally this is discouraged per MOS:COLLAPSE.
  • A major realignment in June 2016 increased the length to 16.55 km (10.28 mi) (10.81 km (6.72 mi) underground, 5.77 km (3.59 mi) elevated). - any way to rephrase this? This consists of several parentheses back to back.
  • (12.40 km (7.71 mi)), etc. - In places where parentheses are nested, I would suggest using |disp=sqbr in the {{convert}} template.
  • The system operates between 06:45 and 21:55 - Here, I would add the relevant timezone.
  • Tourist Smart Card: - Maybe have this as a subsection instead
  • These type of smart cards, are for - The singular/plural is inconsistent and should be "These types of smart cards are for" or "This type of smart card is for"
  • Currently, Presently, Recently, etc - as of when? There are a bunch of these in the article.
  • Indian Railways gave a go-ahead to the proposal, and installation work is supposed to be complete within 2–3 years - from what date?
  • Also, Indian Railways - I'd advice against starting a sentence with "Also", and suggest "In addition".
  • All these lead to snags, delays and accidents - "All of these factors have lead to..."
done ❯❯❯   S A H A 14:40, 29 July 2020 (UTC)[reply]
also, I would like to add that, it's better to keep the route map collapsed, since its big. ❯❯❯   S A H A 18:41, 29 July 2020 (UTC)[reply]

@ArnabSaha: On Discord, SounderBruce pointed out a few more MOS issues. I have fixed most of these, but looking again, there are still a few concerns I had:

  • Consider converting the bullet lists to prose.
  • (about 4 km (2.5 mi) shorter than the current East-West Corridor) - should the outer parentheses instead be dashes, commas, or other punctuation?
  • Presently truncated till Howrah Maidan - truncated past Howrah Maidan?
  • It uses the five-and-a-half-foot (1.7-metre) Indian gauge, a broad gauge rolling stock. - Technically the track isn't itself "rolling stock", so you can cut that. Rolling stock refers to the trains.

I didn't find any glaring errors, and I still think this is nearing GA status, though Sounder might think differently. Hopefully we can straighten out these issues before promotion. epicgenius (talk) 00:51, 30 July 2020 (UTC)[reply]

Epicgenius,
  1. the 1971 masterplan was from Saltlake/bidhannagar to ramrajatala. (google map). but when the line was sanction in 2008, it was till howrah maidan. in future, it might go to ramrajatala (the section was surveyed again in 2012) ❯❯❯   S A H A 08:17, 30 July 2020 (UTC)[reply]
    ArnabSaha, All right. So it would be Salt Lake to Howrah Maidan instead of the full route? Is that correct? epicgenius (talk) 14:11, 30 July 2020 (UTC)[reply]
    Epicgenius, ya. but calling it full route might be wrong. the 2008 plan was from saltlake to howrah maidan only. ramrajatala will be an extension of it. ❯❯❯   S A H A 14:42, 30 July 2020 (UTC)[reply]
2. actually this is a wrong sentence. The Kolkata Metro Line 1 uses broad gauge tracks, thus broad gauge bogies. but the twist is, the shells are of same dimensions as metre gauge train shell. ❯❯❯   S A H A 15:16, 30 July 2020 (UTC)[reply]

POV and coverage

[edit]

No issues here.

References

[edit]
  • Some of these references do not have dates and some do. Same inconsistencies go with authors, and even access dates. This should generally be consistent.
  • Also, check that reference formatting is consistent. For telegraphindia.com, I see such different formatting as "The Telegraph.", "The Telegraph. Calcutta, India." and "www.telegraphindia.com"
  • The Times of India references need to be formatted better.
  • Is ref 10 actually to web.archive.org, or is it to a different website?
  • Ref 13 should be formatted, because readers can see the bare url.
  • Some of these titles are in all-caps and should be title case.

Overall, the formatting needs a bit of work. epicgenius (talk) 21:48, 28 July 2020 (UTC)[reply]

  • Given this is a recent GA, everything is fine except I am having trouble finding a reference that clearly supports the claim (present only in lead and unreferenced) that it was the first proposed system of this type in India? No qualms about it being the first operational, but can we get a quote for the 'first proposed'? If not I suggest this claim is removed from hook and the lead. The QPQ check tool is broken (or simply fails to confirm the nom has never submitted a DYK before), so I am assuming QPQ is not needed (But it is always welcome!). --Piotr Konieczny aka Prokonsul Piotrus| reply here 02:37, 7 August 2020 (UTC)[reply]
Piotrus, Hi. it was proposed by the British in 1919-20. see the "early attempts" section. also, this is my 3rd dyk, so didnt do qpq. ❯❯❯   S A H A 09:34, 7 August 2020 (UTC)[reply]
ArnabSaha But does the source clearly say it was the first proposed, or that no other propositions of its type were made before? --Piotr Konieczny aka Prokonsul Piotrus| reply here 01:11, 8 August 2020 (UTC)[reply]
Piotrus, till date no other document has been found. no sources mention any other cities. also, Kolkata was the capital of India till 1911, the British used to build things in Kolkata (example-Tram). the imes of India and theprint sources might help. it says
1) "As per records, for the British, ... They were keen that people avoid the additional expenses of of living in the city and migrate to places like ‘Dum Dum an Baraset"
2) "The underwater tube rail in Kolkata was planned by the British government when they were building a tunnel under the Thames river in London"
3) "the East-West Metro project across the Hooghly was conceptualised by the British in 1921, at the same time as the river Thames was being tunnelled in London" ❯❯❯   S A H A 06:33, 8 August 2020 (UTC)[reply]
ArnabSaha Hmmm. I'll ping another experienced DYK reviewer User:Yoninah for the second opinion whether the word proposed is ok. I am still concerned that if no source says so outright it borders on WP:OR. Lack of source to the contrary is not necessarily a confirmation of the fact. --Piotr Konieczny aka Prokonsul Piotrus| reply here 02:15, 9 August 2020 (UTC)[reply]
Piotrus, OK. also, I checked multiple Indian cities article, no one mentions before Kolkata. ❯❯❯   S A H A 04:45, 9 August 2020 (UTC)[reply]
For what it is worth, I think you are right, but that doesn't mean we can say so per WP:OR. Which is why I asked for another opinion on this. WP:NOTTRUTH etc. --Piotr Konieczny aka Prokonsul Piotrus| reply here 04:49, 9 August 2020 (UTC)[reply]
I have 1 more thing to add. Even if the British proposal source is controversial, the 1950 Indian proposal can be considered. As per the official website, "It was Dr. B.C. Roy, the then Chief Minister of West Bengal, who for the first time conceived the idea in 1949 of building an Underground Railway" and "With a view to finding out an alternative solution to alleviate the suffering of the Kolkatans, the Metropolitan Transport Project (Rlys) was set up in 1969." ❯❯❯   S A H A 07:54, 9 August 2020 (UTC)[reply]
@Piotrus and Yoninah: sir/ma'am, the DYK is stuck. ❯❯❯   S A H A 09:13, 16 August 2020 (UTC)[reply]
  • It may be tempting to submit yet another first hook, but you have plenty more in this GA article to write a better hook. This popped out at me:
  • ALT1: ... that as India's first metro, the Kolkata Metro was constructed through trial-and-error over a period of 23 years? Yoninah (talk) 16:59, 16 August 2020 (UTC)[reply]
Yoninah, this one is also good. the first underwater metro thing can also be added. ❯❯❯   S A H A 19:03, 16 August 2020 (UTC)[reply]
Yoninah, partially correct. the 1st line is constructed was underground, with 1 station elevated and 1 at-grade. yes, underwater is still under construction.
@Yoninah and ArnabSaha:. The span of construction, which as you may note can be still ongoing, is IMHO not as interesting as pointing out the uncontroversial time range I propise in the following ALT2 below. What do you think? --Piotr Konieczny aka Prokonsul Piotrus| reply here 01:33, 17 August 2020 (UTC)[reply]
  • ALT2: ...that India's first metro, the Kolkata Metro, was first proposed in 1919 but became operational only in 1984?
Is "ONLY" required here? doesn't seem appropriate. ❯❯❯   S A H A 06:25, 17 August 2020 (UTC)[reply]
"Only" is fine. It turns it into a hook, as opposed to a statement of fact. Yoninah (talk) 11:05, 17 August 2020 (UTC)[reply]
ok then, keep this. ❯❯❯   S A H A 15:02, 17 August 2020 (UTC)[reply]
  • Here is a full review: GA received within 7 days of nomination. New enough, long enough, neutrally written, well referenced, no close paraphrasing seen. Images are freely licensed. I have tagged one sentence as needing an inline citation, as it verifies one of the ALT2 hook facts. No QPQ needed for nominator with less than 5 DYK credits. Yoninah (talk) 17:26, 17 August 2020 (UTC)[reply]
Yoninah, the whole paragraph is a mix of the citations mentioned at the end. ❯❯❯   S A H A 17:59, 17 August 2020 (UTC)[reply]
