Our toddler-aged testers loved how there are so many things to do and press on this toy: spinning the helicopter, pushing the tap for "water", taking out the freight from the train, or just driving the trains and Sir Topham Hat's car around. And no need to worry about complicated track set up - there are none since this age group really just prefers to drive their trains free-style acorss the floor anyway. A great first "train set".
