I removed the following sections that describe a catwalk aboard the Enterprise-D, rather than the catwalk. The latter being an in-universe term, the former a dictionary term.

"The catwalk is the nickname both for a maintenance shaft inside a warp nacelle and for a maintenance walkway on Deck 35 just above the center of the warp core in Main engineering onboard Galaxy-class starships.
In 2368 Lieutenant Commander Geordi La Forge was feeling dizzy and almost fell off the catwalk. He was rescued by Ensign Fletcher. (TNG: "Cause and Effect")"

It doesn't seem right that catwalk is in Staship Sections and not allow catwalks from other ships. This needs to either be changed to something like "Nx class catwalk" like we have for decks or making it something like tree, where there is an article for catwalks in general, that then directs to articles on different catwalks. – Saphsaph 03:13, 10 November 2008 (UTC)
