How much money does Amusement Park give when you play it?
It gives 1 coin for itself plus the base value of a Train card you have in play. With an Express Train (2) that is 3 coins, and with a Limited Express Train (value 3, not its cost of 6) each Amusement Park gives 4. Amusement Parks do not count each other. It gains no card and leaves no lasting effect.
