Talk:British Rail Class 377

WCML to Watford?

Surely the Gatwick-Watford service doesn't use the WCML? Or am I a silly old fool? Dyakson 01:02, 28 August 2007 (UTC)

It uses the slow lines from Wilsdeen Junction to Watford Junction as i understand, although they use the bay platforms at Watford Junction. They run route training further up the WCML incase of the bay platforms being unavailable. Its the curtailment of an earlier service that used to run all the way up to the bay platforms at Rugby.

Speed run?

"Note: units 377472 and 377474 have 'speed run' branding in reference to these units forming the record breaking London to Brighton run."

Might be an idea actually to explain in the article what that was! 86.143.48.85 (talk) 21:44, 16 November 2008 (UTC)

British Rail?

Why does the title include "British Rail" (capital B, capital R) - when the Class 377 was ordered after the break-up of British Rail which was completed in 1997? I would agree that "Class 377" on its own as an article title could do with some qualification to associate it with British rolling stock, but naming it after a defunct organisation seems to lack rationale, other than backwards compatability with pre-privatisation rolling stock articles. -- Timberframe (talk) 09:10, 16 February 2009 (UTC)

I suggest you raise this at the UK talk page as it affects other articles. Bhtpbank (talk) 10:48, 16 February 2009 (UTC)

Though with all due respect this has been talked to death and the general consensus is that the current naming convention is the least of several evils. NRTurner (talk) 12:05, 16 February 2009 (UTC)

Bhtpbank - thanks for the suggestion, I've done so. NRTurner - thanks likewise, for my info, where was the discussion? -- Timberframe (talk) 12:08, 16 February 2009 (UTC)

Coupler Section is muddled

This states "Southern's 375s were all converted to Class 377 when their Tightlock couplers became redundant after the retirement of the "slam-door" stock such as the Class 421."

This doesn't make sense since "slam door" stock from the 1960s (and beyond) didn't have Tightlocks, they were fitted with the earlier Buckeye couplers which needed the units to "ease up" and the manual intervention of a shunter to get them apart. Automatic Tightlocks weren't available until later stock such as Classes 319 & 465, and in any case these were not directly compatible with Buckeyes; an adaptor set consisting of 'Mushroom & Pin' was required to compensate for the geometry and height differences.

Also it should be understood that the main reason for removing Tightlock couplings from the 375 fleet was reliability and maintenance issues. There were some embarrassing instances of 375s coming apart in the early years, and the decision was taken to modify the 375s and abandon Tightlocks on future EMU stock.

Thanks. Any chance you could find some sources that state this? If so, feel free to rewrite it. NRTurner (talk) 10:29, 2 December 2009 (UTC)

Capacity: How many passengers can a 4 carriage unite take? Seated / Standing / Total? Also - how many can 8 / 9 / 12 carriage configurations carry? —Preceding unsigned comment added by 94.170.105.32 (talk) 22:39, 26 July 2010 (UTC)

Hi. Just to let you know, the Commons category for Class 377s is now completely sorted by operator and livery. -mattbuck (Talk) 19:23, 5 August 2010 (UTC)

Performance in the Snow

Perhaps someone knowledgable should write an entry on the technical reasons why Class 377's seem to drop like flys following the first fleck of snow? I spent 10 hours sleeping in one on 02-Dec-2010 following multiple failures of 377's across the Southern Network. Much the same happened the previous year. Davagh (talk) 22:53, 3 December 2010 (UTC)

I assumed it was just a third rail problem. -mattbuck (Talk) 22:55, 3 December 2010 (UTC)

Possible change to the title of this article

This article is currently named in accordance the Wikipedia:WikiProject UK Railways naming conventions for British rolling stock allocated a TOPS number. A proposal to change this convention and/or its scope is being discussed at Wikipedia talk:WikiProject UK Railways#Naming convention, where your comments would be welcome.

Blacklisted Links Found on the Main Page

Cyberbot II has detected that page contains external links that have either been globally or locally blacklisted. Links tend to be blacklisted because they have a history of being spammed, or are highly innappropriate for Wikipedia. This, however, doesn't necessarily mean it's spam, or not a good link. If the link is a good link, you may wish to request whitelisting by going to the request page for whitelisting. If you feel the link being caught by the blacklist is a false positive, or no longer needed on the blacklist, you may request the regex be removed or altered at the blacklist request page. If the link is blacklisted globally and you feel the above applies you may request to whitelist it using the before mentioned request page, or request its removal, or alteration, at the request page on meta. When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags. The whitelisting process can take its time so once a request has been filled out, you may set the invisible parameter on the tag to true.

GPS for passenger doors?

There were media reports that this class would require a GPS signal to know whether it's in a station for the doors to be unlocked. Should this be added in the article or is this normal in britain? If the latter: How is this system called/where ist the article about it? (please ping me for answers, I'm normally not on this language) --nenntmichruhigip (Diskussion) 21:18, 18 March 2015 (UTC)

@Nenntmichruhigip: It's not normal; in fact I don't know of any class that does this. But to add it in, we would need a reliable source, per WP:V. --Redrose64 (talk) 21:38, 18 March 2015 (UTC)

Sure, here it is. I just forgot to link it due to tiredness, sorry. --nenntmichruhigip (Diskussion) 11:25, 19 March 2015 (UTC)

I've just noticed it is already mentioned in the article, but much shorter than I would have expected: "In conjunction with the onboard GPS receiver, Mitrac controls Selective Door Operation (SDO) […]". So maybe someone (with better english and better knowledge of british railways than mine) could add the criticism over there or something? --nenntmichruhigip (Diskussion) 12:33, 19 March 2015 (UTC)

Well this is a late reply, but there seems to be some confusion that needs clearing up. This is not limited to Class 377s. AFAIAA all recently manufactured trains using Selective Door Operation need to have a GPS fix. To my knowledge the Bombardier & Siemens fleets in the UK do. SDO is intended to ensure that only those doors which are over a platform can be 'released'. So for example, a 12 car train could stop at a 4 car platform and the system would only allow 4 carriages to release when the driver gave a door open command - the other 8 carriages would remain locked. The data for each station is programmed into the SDO. Obviously the train needs to know where it is and which direction it is travelling in (because different platforms at a station aren't always the same length!). If the GPS loses its fix, the SDO won't respond to the door open command from the driver. This can happen whenever the view of the sky is obstructed and not enough satellites can be 'seen'. Without being specific, using MITRAC it's necessary to scroll through a list of locations where a release is allowed, pick the one you're at, confirm that you are really there and you really want to do it (as you are over riding a safety system), and select a manual release. It's not a problem, but it does tend to waste time and frustrate the passengers as they have to wait for the doors to be released. Personally speaking I didn't feel the urge to put this on Wiki as I don't think it's a big deal, and it's already touched upon in Selective door operation#Control by GPS, HTH, Dr Sludge (talk) 10:07, 28 November 2016 (UTC)

Update main image and add interior images

Consensus reached

 – Main infobox images have now been changed.Class455 (talk

I would like to update the main image with a photo of Class 377/6 No. 377622 at London Bridge and the interior of the Class 377/6. In addition to this, I would like to add a couple of interior shots from Class 377/4 to the article, these being of a First Class cabin and a Standard Class saloon. talk 17:40, 16 February 2017 (GMT) PeterSkuce (talk) 17:39, 16 February 2017 (UTC)

• Support - Seen the images in a previous diff before I told the editor to come here to gain consensus, they look pretty good to me, however the quality of the First Class image could be better. PeterSkuce, could you perhaps cut and paste the links from the previous diffs so that other editors can see the images you're talking about? Class455 (talk|stand clear of the doors!) 17:43, 16 February 2017 (UTC)
• I support changing the interior images, but I don't feel the London Bridge image is superior to any of the exterior images in the article as is. -mattbuck (Talk) 19:22, 16 February 2017 (UTC)

Here are the images that I would like to add:

PeterSkuce (talk) 18:05, 16 February 2017 (UTC)

What about this image for the top photo:

This image would go along with the Class 377/6 MSO Interior image does everyone agree with me?

PeterSkuce (talk) 21:14, 16 February 2017 (UTC)

Here is the interior image:

PeterSkuce (talk) 22:14, 16 February 2017 (UTC)

The image of the 377/6 at Clapham Junction looks good, but I'm slightly worried that it might be a copyright violation as it was taken from someone's Flickr. However, I have seen the same person's work on other Wiki pages, so I'm not sure about that. Class455 (talk|stand clear of the doors!) 22:31, 16 February 2017 (UTC)

It was flickr reviewed, and in fact is still CC-BY-SA on Flickr, so there's no copyright issue. I don't believe it's truly necessary to show the same subclass interior as exterior in the infobox. I'm not sold on the Au Morandarte pic, but the best other /6 I can find is File:Battersea Park railway station MMB 30 377605.jpg and that's rather too head-on I feel. The subclasses look pretty much identical bar number of carriages, just find the best outside view of any Southern 377. -mattbuck (Talk) 23:03, 16 February 2017 (UTC)

@Mattbuck: Great shot there! I think thats a good image as well we could use for the infobox. Class455 (talk|stand clear of the doors!) 23:07, 16 February 2017 (UTC)

Both the Class 377/6 and 377/7 have different bodyside windows and marker light clusters. I do not mind if we decide to use 377605 at Battersea Park station.

PeterSkuce (talk) 23:13, 16 February 2017 (UTC)

Yeah, I'm fine with that too, as well as your interior images. Class455 (talk|stand clear of the doors!) 23:22, 16 February 2017 (UTC)

I have amended both the main image and the interior image.

Update interior image

For some time now, I have thought that the interior image of a class 377/6 is not as representative of the fleet as it could be. That is because out of the 216 class 377 units operated by souther, class 377/6s and class 377/7s only make up 15% of the fleet. I believe it should be changed to instead show an image inside a class 377/1, 377/2 or 377/4 (although not a 377/3, which has a different layout), which collectively make up 71% of the southern class 377 fleet (higher if southeastern's class 377/5s with largely the same layout are added). A suggestion of what could be used instead, from wikimedia commons is shown right next to this text in the reference[1]. If the image is changed, then the old image could still be included in the article, just lower down. Lawrence 979 (talk) 17:44, 26 May 2024 (UTC)
