great
My friend's son was very happy with it. Fast service from bol.com.
nice train
A small, but so cute, gift to give in between. It's so fun that we're going to buy another one to have a train set too.
LEGO, you're never too old for it
My son, now 26 years old, is a collector, especially of Lego. He likes both the technical and all the "regular" special models. So he was very happy with his Christmas present.
nice train
It's very fun to play with and, if you actually buy 2 boxes, they can have hours of fun and create many different variations.
Cute little locomotive.
This cute locomotive looks great with everything, especially if you buy a second box and build a wagon. Add a few more and you'll have a whole train of wagons with a locomotive that runs through the room :)
