Hochgeschwindigkeitszüge

It looks like the topic name is incomplete: “Hochgeschwindi…” Could you please confirm the intended subject? For example, you might mean Hochgeschwindigkeitsbahn (high-speed rail) or Hochgeschwindigkeitszug (high-speed train), or another topic entirely. If you provide the full title, I can generate a concise, neutral, wiki-style article under 300 words.
