"My 3 year old loves this train but unfortunately it's also caused a lot of tears by breaking down twice within 8 weeks. With the first set we got, the sound stopped working after 2 days. Luckily we were able to get a replacement from the store we bought it from, after a lot of arguing on our part and it took 3 weeks for the replacement set get to us. 2 weeks into the new set the action bricks have now stopped working and the store won't replace it again so we either just have to live with it not really working or shell out another $99 for a whole new set. It's a shame because it's great fun and we already bought a couple of the extension options."
