Canal at Trollhattan

We took the train from Oslo to Trollhattan, Sweden, riding through green farmland and small forests.
Why Trollhatten? It doesn't matter where you decide to go, does it? It's all going to be new and interesting.
Trollhattan is a small town of canals and well-preserved industrial artifacts like a railroad bridge that used to swing out from one end across the canal to connect to a railroad turntable on the other side so you could turn the engine around when you wanted to.
For us, the only turning we're going to do is to the Saab museum to see the world's oldest Saab.
