Have the VTech park and rail set for our 2.5 years old children bought. The streets hold together unfortunately not well enough so that the children resent repeatedly since they differ partly at play. I doubt that this is suitable for a 1 year old child. For car park I can say that can not go on the straight sloping line the cars as they stick to the joints of the parts.
Now we have the toy and want it / can also take away the children no longer have to live with it to build the parts together again until the kids can build themselves. Otherwise, they like to play with it, but is worth no more than 2 stars.
