My son loves trains, as I’m sure your son does. If he does, I’m sure you’ll love this web site I’m posting a link to below!! It’s really neat. They have paper models that you can make of the TGV trains. You can print out the parts of the train and then you put together. They are small, so you’ll probably have to do the majority of the work, but I’m sure you’ll son (or daughter) would love to play with the trains afterwards.
