Mid

This article has been rated as Mid-importance on the project's importance scale.

This article lacks references.

Not general

Artical does only discuss wheelset in Australia. European railroads and tramways are not described. —Preceding unsigned comment added by Pechristener (talk • contribs) 18:15, 29 January 2008 (UTC)[reply]

Severe problems on the heavy haul iron ore railways in the Pilbara region (heavy traffic and high axle loads) led to studies of the wheel-rail interface at Melbourne University and later the establishment of the International Heavy Haul Association so that all heavy haul railways could swap notes.

references, removals etc

Each wheelset for a standard class rail carriage in the UK costs on average £16,000 which for the longevity of the sets is one of the most efficient in the transport system today at the average cost of £4000 per wheel that lasts over 1,500,000 hours in service.

What is this nonsense supposed to mean?FengRail (talk) 00:07, 14 April 2009 (UTC)[reply]

== Wheel and rail profiles ==
Wheel and rail profiles aren't straight, but follow specific shapes that have been found to follow curves and reduce hunting, and to reduce wear and tear.
Heavy traffic and high axle loads on iron ore railways in the Pilbara cause serious damage to wheels and rails, leading to fundamental research on the Rail-Wheel Interface. This information has been made available to the world through the International Heavy Haul Association (IHHA).

This section seems to assume that the "Pilbara" is the source of rail-wheel interface research. This is just nonsense.FengRail (talk) 00:08, 14 April 2009 (UTC)[reply]

== Hub to rim connection == The metal connecting the hub of the wheel to the rim is thin to save weight. Originally it was straight. However, wheels get hot when brakes are applied, and the straight connection caused stresses that could cause fractures. It was then realized that the connection between hub and rim could be made with a curve which could absorb such heat stresses better and safer. ^{[citation needed]}

International compatibility of railway wheel flanges

By chance, my attention was drawn to the fact that american vehicles cannot roll on european tracks, despite their identic gauge, because their flanges are wider (also, some of them are too heavy). Likewise, european vehicles can't roll in America.

On the other hand, russian vehicles seem to be able to roll on european tracks, after their gauge has been adapted - this I would conclude from Russia's Talgo technology plans? — Preceding unsigned comment added by 190.120.231.38 (talk) 05:05, 23 March 2012 (UTC)[reply]

American vehicles can roll in Europe and other way around if their wheels and are changed. Also other rules for couplers and loading gauge must be followed. This is mostly done if selling vehicles between the countries, since it involves special measures for the loading and unloading. Normal cargo are transported in containers. -- BIL (talk) 07:01, 24 May 2012 (UTC)[reply]

European equipment is used on the GO train and I doubt if the wheels were changed. similarly a British steam train did an exhibition run in the US and Canada in 1969 and AMTRAK at one time ran French turbo trains. Peter Horn User talk 00:32, 3 April 2014 (UTC)[reply]

Oops, make that O-train. Peter Horn User talk 00:37, 3 April 2014 (UTC)[reply]

Curves link to Civil Engineering#Surveying

I'm wondering why does the word 'curves' in "steering the wheelset around curves" link to the article about Civil engineering - Surveying?

Semi-Conical shape: Word:Conicity

I just worked on some cleanup of the Semi-Conical shape section and the word Conicity stood out as something I didn't understand. In the process of linking to "Tire uniformity" I began to doubt if this is the best word to describe the shape. If someone with knowledge in this topic can verify please have a look.Figure81 (talk) 12:20, 6 September 2015 (UTC)[reply]

Okay...and?

Okay, so Queenstown Railways uses "Grover's Bogies". Great. So, WHAT are they, how and why are they used, and why is this relevant to the article on wheelsets, and not the one on bogies? As far as I can see the wheelsets themselves are the same as most, by one definition, and if one wants to say that they don't count as bogies because they are single-axle, then why are they called "bogies"? This section doesn't seem to contribute much to the article, really.AnnaGoFast (talk) 05:53, 31 July 2017 (UTC)[reply]
