It definitely took longer than expected (2 years), but the table is finished. It originally started as a train table for the kids, but it turned out to be a really nice piece of furniture, and is contending for the nicest in the house. I think the table will be a general purpose table that the kids can play on as they see fit and there will not be any restrictions on what they want to do on it (That is why there is a pretty thick layer of polyurethane all over the table). It looks great and I hope the kids use it as a nice play surface for legos, trains, coloring, painting, or whatever their imaginations can think of.
Here was the original Sketchup drawing of the table two years ago. It turned out to be pretty close.
