Three Dog Night

My oldest son is an engineer for BNSF and his son (5) is a train lover too. Last fall when at their house I noticed grandson had a toy with geometric puzzles and one was a train. I had just taken a Barn Block painting class and thought why not. Lost a little of train since my board is square and puzzle was more retangular but turned out OK.
Just finished yesterday and will gift to them on Christmas, it's painted with exterior paint so can be indoor or outdoor.
