Images
[edit]- There are some issues with the article images that need addressing:
- There are an over-abundance of images. While images can add to an article too many are contrary to "what Wikipedia is not".
- Duplicate images are certainly not needed.
- Foreign language captions. Bogie extra images pool imported from de:Drehgestell was added to the "Images gallery" section. The captions on these images are in German and not English. This begs a "Please do not contribute text in a foreign language to English Wikipedia. Your contributions are more than welcome at a Wikipedia in your language. Thank you." -- Otr500 (talk) 14:29, 19 May 2019 (UTC)
- Does anybody want to correct these issues and trim some of the excessive images or just accept the ones I remove from the article? Otr500 (talk) 01:05, 22 May 2019 (UTC)
Flatbed trolley
[edit]@Bonadea: Flatbed trolley Quote:"Without a flat surface it becomes an "open frame" trolley and without a handle it is a bogie or dolly.[1] Peter Horn User talk 13:47, 20 September 2019 (UTC)

Three axle bogies
[edit]Three axle bogies are available in the USA[1] [2] Peter Horn User talk 11:25, 29 July 2025 (UTC)
- In North America, including Mexico, they are used on mainline diesel electric locomotives and special freight cars. Peter Horn User talk 20:56, 1 August 2025 (UTC)
- They've been widely used in most places with bogies and heavier stock. Both for early passenger coaches (Pullman used them), and for heavy transport well cars. Andy Dingley (talk) 11:32, 30 July 2025 (UTC)
- There's a whole book about British Pullman cars with six-wheel bogies - Ford, Antony M. (2008). Pullman Profile No. 1: The 12-wheel Cars. Southampton: Noodle Books. ISBN 978-1-906419-00-4. - 192 pages, with diagrams, mnochrome photos and colour illustrations. The London and North Western Railway and its successor the London, Midland and Scottish Railway (LMS) both used six-wheel bogies for their longest passenger coaches - those with underframes measuring 65 feet 6 inches (19.96 m) to 69 feet (21.03 m) over headstocks. Generally, these were sleeping cars and restaurant cars, and the first were built in 1897. The last of the twelve-wheel LMS sleeping cars was not taken out of service until the mid-1970s. --Redrose64 🌹 (talk) 17:58, 30 July 2025 (UTC)
Wheelsets per bogie
[edit]I'd like to object to the assumption that a bogie must have at least two wheelsets. I just noticed that this was changed a year or two ago, and I hope we can change it back again.
The main characteristic of a bogie is a subframe which can rotate independently of the vehicle body and thus allow the wheels to more freely follow the path of the track and come close to ideal radial steering. Until recently, this was mainly done passively, with two or more wheelsets forming a unit with stable compromise of good driving characteristics in curves and on straight track, but there's nothing that says that a bogie must necessarily have more than one wheelset. A bogie with a single set of independently rotating wheels can achieve essentially the same effect, provided it's controlled in the curve somehow, either passively according to the angle between to cars, or actively using a control system like that used by the NGT bogie or the SILK bogies used by TELLi . So yes, most bogies have two or more wheelsets, but if we look at what the original point of a bogie is and also consider recent developments in bogie desgin, it's clear that the definition now used in the bogie article is too limiting.
I'm a very occasional contributor, so I'm not sure how this kind of thing is normally done, but I hope we can clear this up and that I'm going about it in something approaching the right way. Vankrugermeer (talk) 22:09, 22 November 2025 (UTC)
