kilometers!

In the UK we use miles and miles per hour. So why does the entry use kilometers with miles in brackets? Also, the numbers are incorrect, as they are different on the HS1 official web site. — Preceding unsigned comment added by 92.21.15.48 (talk) 22:52, 10 February 2020 (UTC)[reply]

I believe HS1 was built and is operated using kilometres first, whereas the rest of the British railway network still uses miles. NemesisAT (talk) 12:48, 30 March 2021 (UTC)[reply]

However they still use the miles when operating. QuarioQuario54321 (talk) 22:31, 29 January 2023 (UTC)[reply]

@QuarioQuario54321 Not the case - the Transmission Voie-Machine signalling system used on HS1 uses kilometres per hour. "The maximum permitted speed for each running line is shown in kilometres per hour (km/h)." All distances are also in kilometres per hour "Distances on the main HS1 route are shown in kilometres and metres based on a ‘0’ datum point at St. Pancras International station." Turini2 (talk) 22:35, 29 January 2023 (UTC)[reply]

The article is written with kilometres as the predominant measurement (as per HS1), with relevant conversions shown where necessary. Turini2 (talk) 22:38, 29 January 2023 (UTC)[reply]

Just jumping in here to add further support for the article's main units of measurement being metric. Kennethmac2000 (talk) 18:00, 21 February 2025 (UTC)[reply]

Ownership

@AlbusWulfricDumbledore I reverted your edit because a) there was no reference b) it implied that the 2017 sale was to the Korean Pension fund, not the Ontario teachers Pension fund. Turini2 (talk) 17:49, 9 April 2023 (UTC)[reply]

The existing reference in text explained it, added a non-paywall reference. If you paused to read the existing source while reverting - it was Korean pension fund it was sold to in 2017 (consortium of funds) from the previous consortium involving the Ontario fund AlbusWulfricDumbledore (talk) 17:53, 9 April 2023 (UTC)[reply]

Thanks for explaining! Turini2 (talk) 17:54, 9 April 2023 (UTC)[reply]

No worries! Thanks for pointing out the poor reference AlbusWulfricDumbledore (talk) 18:03, 9 April 2023 (UTC)[reply]

Stations

Ashford and Ebbsfleet stations have not had Eurostar services since 2020 and there are no fixed dates for their re-opening. St Pancras is currently the only functioning Eurostar station in the UK. 2A00:23C8:8A92:7C01:C881:6B24:AD97:358C (talk) 21:00, 19 September 2023 (UTC)[reply]

There's been no formal announcement of closure, I think it's reasonable to note that the stations are temporarily closed for Eurostar services. Turini2 (talk) 10:11, 20 September 2023 (UTC)[reply]

There is a discussion at Wikipedia talk:WikiProject UK Railways#Should CTRL be put first in the lead or HS1? relating to this article. Dank Jae 14:23, 19 February 2024 (UTC)[reply]

CTRL or London St Pancras Highspeed?

Is this article about the piece of physical infrastructure known as the Channel Tunnel Rail Link, or is it about the company known as London St Pancras Highspeed? It currently seems to be conflating the two things.

I would suggest these two concepts are separated out into two separate articles. Kennethmac2000 (talk) 18:02, 21 February 2025 (UTC)[reply]
