Talk:Locomotive frame

Needs more info

I cannot believe that this is all wiki has to say on the subject of locomotive frames. And this is simply a terrible description of a bar frame. "These were made of two steel bars which are usually 4–7 in (100–180 mm) thick"? No, they are not made up from 'two bars', they are open girder or framework structures made by welding an assemblage of smaller bars of iron into a rigid assembly, as opposed to stacked and cut iron plates riveted together. It almost sounds like the person who wrote that paragraph actually had no idea what a bar frame was, and really assumed it was just two 4-7in bars laid down parallel to each other. That's what it sounds like it is saying. The photo helps a bit, but only if you know what you're looking at. A new reader who looks at that photo trying to figure out which piece is the "two bars" is going to be sadly confused.

Here is a photo of a model bar frame: https://www.cumberlandmodelengineering.com/_derived/Dave'sLocosBrass.html_txt_G%20Class%20Proto%20Frame%20(front%202).gif Note that there ARE traditionally two main longitudinal bars, but the entire assembly is the frame.

We should be able to write up a bit more than we presently have. --Redrose64 🌹 (talk) 19:01, 16 November 2024 (UTC)
