Excellent Toy!!!
This is an excellent toy for babies 6 months and older. It is very durable and well made. The animals are a bit heavy for younger babies but they will last a long time. I didn't notice any trouble with it moving on carpet, but I will say that it does take a long time to start moving. You have to wait for it to play a song before it will start to move. You can also buy additional cars and animals to add to the train set. My son loves to play with it and throw it across the room. It stills works great after all the abuse that he has inflicted upon it.

Learning about animals is REALLY. LOTS. OF FUN (toot toot)
Whoever sang the songs that this train plays has really earned her dough. She warbles, she falsettos, she vibratos.. she sells it, man. She's a much more enthusiastic singer than the woman in the Fisher Price Fake Noah's Ark, I tell you this much. I really appreciate when someone goes above and beyond the call of duty for things that don't really matter, like singing a stupid animal song on a kid's toy.

The toy itself is good, as well. My son loves to throw the gorilla at me (I think the Gorilla is actually from the fake Noah's Ark) and my daughter likes to throw the little chimp at my face. It teaches hand-eye coordination and.. ?
I'm not sure. Learning about animals, I guess.

Unfortunately the product was damaged upon arrival and I had to return it. Once I got the new one it was an awesome toy and my son loves it. Catchy tune as well.

I love this train!!
We bought this train for our six month old daughter. It arrived way faster than I expected. For the price that I paid I didn't think it would be as big or as nice as it is. We have so much fun playing with this toy. It doesn't get put away. Every day when she is on the floor she always manages to get to the train. I turned off the moving wheels at the moment. She's not quite crawling and she got frustrated when it went away from her. She loves playing the different songs and hitting the whistle that makes animal sounds. She figured it out within a couple of days. I haven't seen a need to get the other cars for anything other than the fact that they're super cute!! We absolutely love this!! There is one con though. The songs get stuck in your head for days on end, since they're so catchy and fun to sing along with.

FP Learning Train, animals
My son got this for Christmas when he was 8-9 mos old. He has played with it pretty frequently, but I wouldnt say that it is his favorite toy. I did get some of the additional animals as well and know that he is 14 mos he seems to play with these a little more. This toy is well constructed and durable, but not that engaging for an active little man.
