A train company wants a class diagram that models the relationship between long-distance train trips and passengers. The long-distance train has: a unique trip identifier (e.g. AL456); a model code for the engine (e.g. E67) and a model code (e.g. P9754) for each passenger car; two different areas ("Standard" and "Executive"): Executive 20 seats, Standard 400 seats. Each passenger: has contact details (email + phone number); purchases a ticket ("Standard" or "Executive") and is given a seat number (e.g. 25D); may be a frequent traveller.
