Making tracks

Last week Joshua and I picked this up from the library for the holidays and we're very impressed. The text is very informative (I get Joshua to read the titles and I read the paragraphs). The best parts are the projects scattered throughout with instructions to build your own cardboard railway tracks, underframe with wheels scaled for the track, locomotive, caboose (brake van) and a load-bearing tunnel. So far Joshua has been working with Jeff to make the tracks and part of the underframe, and is pestering us every minute of the day, it seems, to do some more. I'll post photos when he gets further along.
