Opa is my husband and Nana is myself. This blog started when my husband built a garden railway in our back yard. When he was planning it we talked a lot about when we have grand children that it would have to be open for them to touch and play with. We've learned from each other about our ideas of children playing with the 'trains' and have practice sessions with friends bringing their children to visit.
Watch for more to come - it's a big country!
