Deletion of Steam locomotive components

Comment: Some folks seem to be a bit confused about what this article (and hence, nomination) is about. Nobody is questioning the notability of steam locomotive, steam engine, or even numerous components themselves like trailing wheel. But there is no indication that this random list of components passes  (or ). There is also the OR concern with the claim that the article presents a (list) of "main components found on a typical steam locomotive." Who chose those elements? Presumably, the author of the diagram, who then decided to create the article. That's pure OR, making a diagram and then describing it on Wikipedia. And in fact, the OR nature of this is stressed through history: https://en.wikipedia.org/w/index.php?title=Steam_locomotive_components&oldid=6179604 this was created in 2004 as a diagram description with no references. Over the years, the diagram has changed, and the list of components grew from 34 to 48, with not a single source confirming that 34 (or 48) elements in question are typical. And why, pray tell, are we supposed to believe the current list of 48 elements is correct? Why doesn't it mention the Kylpor ejector or the larger concept of the steam locomotive exhaust system? This is OR mess top to bottom. This or a similar diagram can be preserved and used in the article on steam locomotive, it doesn't need it own stand-alone article

Comment: needs too be rewritten if to be kept, otherwise it seem like non-encyclopedic trivia, mainly when lists are defined not by a single technical standard but by Wikipedians based on their personal experience/opinions/research =
