very impressived, the quality of the finished build would make you think it was a kit. 3.1 is not a bad time at all considering the shape and the distance it had to travel.
I think this type of featured vehicle would be very cool. Having a 7 year old this would really get him involved. And as you stated in how you built it, its easy and supplies are available to anyone quite easily. Be nice to see all different Tomas the train characters going down the track.
Congrats on the build, and I'm anxious to meet you all for the first time at Mid America
