Here's how to format train names:
* Use quotation marks: "The Orient Express," "The Flying Scotsman," "The Hogwarts Express"
* Capitalize proper nouns: The Orient Express, the Flying Scotsman, the Hogwarts Express
Examples:
* I rode the "Orient Express" from Paris to Istanbul.
* The "Flying Scotsman" is a famous British locomotive.
* Have you seen the "Hogwarts Express" in the Harry Potter movies?
Exceptions:
* Some train names might be part of a larger title, such as a book or movie, in which case they might follow the style guide of the title.
* If you're referring to a specific train line or company name, it should be treated as a proper noun and capitalized. For example, "I took the Amtrak train from New York to Boston."
