Out-of-date information

The list of trains built dates back to 2006, but a number of new types have been built since then, so the list will need to be updated. The Navigation box lists all the trains mentioned on the Japanese article, so it should be more or less up-to-date. --DAJF (talk) 15:05, 2 March 2009 (UTC)[reply]

Chassis

Most train carriages have a chassis. When looking at the A-train construction video on Hitachi's website there appears to be no chassis. Is the A-train really monocoque construction? If so, this would be a significant design feature and ought to be mentioned in the article. FreeFlow99 (talk) 10:19, 2 January 2020 (UTC)[reply]

Accidents and defects deleted

The following was deleted very shortly after I added it to the the United Kingdom section (copied from British Rail Class 800, which is a Hitachi A-class). The edit summary was "Reverted good faith edits by Pol098 (talk): Not sure direct duplication of content is useful, not clear that this is relevant to the A-train family as a whole and could therefore be covered in much less detail, if at all".

I included it in this article as defects in this type of train are highly relevant to the article; removing these paragraphs can be viewed as "sanitising" the article, removing sourced material about problems and issues (trains possibly susceptible to cracking, and not designed to withstand a collision at low speed. (Later checking user contributions, I find no indication that the deletion was not in good faith.)

If anyone wants to reinstate this, the following paragraphs were copied verbatim from the article, and can just be copied back after the paragraph beginning "Many other UK operators have bid" and before the table.

The effect of a collision due to driver error when a class 800 ran into the back of another train was exacerbated by the design of the Class 800 as crashworthiness requirements did not require the effects of a collision at less than 23.5 mph (36 kph) to be taken into account, nor did it include specific criteria for assessing the derailment performance.[1][2][3][4]

On 26 April 2021 GWR temporarily withdrew some 5-car Class 800 sets from service, following the finding of cracks in the yaw damper bolsters.[5][6]

On 8 May 2021, Great Western Railway, London North Eastern Railway and Hull Trains suspended use of their Class 800 trains after cracks were discovered on the welds of the jacking points on a GWR trainset undergoing maintenance. Significant disruption was caused by cancellations of trains between London, to Scotland and to the west of the UK.[7][8][9]

Best wishes, Pol098 (talk) 12:30, 8 May 2021 (UTC)[reply]

@Pol098: I just don't see the value or relevance in repeating this (especially verbatim) from the Class 800 article. That article is already linked from here and is clearly the most appropriate place to cover it, particularly in the absence of any indication (at this time) that this is fundamentally related to the "A-train" family as a whole. For example other UK A-train based classes (395, 385 etc.) haven't been affected as far as I know. If my objections aren't widely shared and you feel this is still important for inclusion you could re-add it, I wouldn't fight to keep it out. Beevil (talk) 12:59, 8 May 2021 (UTC)[reply]
