thomas and friends mini series

We've just discovered these mini trains last weekend. Our 3-year old is obsessed with his mini trains! We have the wooden track, the blue track, the brown track, and the silver track. We hope they come out with tracks for these minis trains. We have one case full of the minis already and going back today to get more now that we have a list compiled from this forum. Thank you so much for the clue about the numbers on the bag as well as the detailed lists and photos of the trains in the series!
