What route would you take to connect all these lines? What would you count while travelling?

On another train of thought: The route may not always be obvious. Check the indicator board for details that may assist in planning your trip.

Two of the maps are Brussels and Toronto. Journey from Frankston to Airport, changing lines at stations with similar names. Read the indicated letter from the indicated stations for each leg of the journey. Make sure you extend your journey to reach the end of the line.
