As you go into longleat you purchase a passport ticket which allows you into various parts/attractions, one of the attractions is the model railway. This is a railway with wee individual carridges watch your head on the roof as you get in. The journey takes you past the lake and past a field that has different cardboard cut outs of lord bath etc. The railway was good fun for the children and the adults it takes approximately 15 minutes i think. There is a wee shop where you can purchase train whistles, thomas the tank engine products etc.
