There are very few narrow guage steam trains still in operation around the world. One of them is the Apple Express, which runs from PE to Thornhill and back over weekends. It is a great trip giving one a leisurely view of the surroundling countryside, from a perspective you don't usually see.
One of the highlights is the opportunity to walk across the railway bridge over the van Standens River Gorge
This picture of Granny Smith was taken at Loerie, during the Great Train Race several years back. It was a real fun event, where up to 600 teams of relay runners, raced the train to Loerie. Unfortunately the race fell foul of internal politics with Athletics South Africa and was subsequently derailed.
