Jacobite Steam Train, Scotland

The Jacobite Steam Train delivers the most magical railway experience in Britain, crossing the iconic Glenfinnan Viaduct with Ben Nevis and Loch Shiel as backdrops. This real-life Hogwarts Express carries 180,000 passengers annually, proving J.K. Rowling didn't need to invent the magic — Scotland already had it. Its steam locomotive produces 2,400 horsepower, making it 50% more powerful than any other heritage train on this list, though its 84-kilometer route is 35 times shorter than #5 The Ghan's cross-continental marathon.
