Title: Add Two Struct Objects

I'm not too sure if I understood the instructions correctly or where you were trying to go with:
passengers = [Passenger.new(name: 'Bill Smith'), Passenger.new(name: 'Sarah Robot')]
Train.new( passengers, {destination: 'New York', number_of_engines: 4, caboose: true, number_of_cars: 5})
