But for all the times I've been separated and reunited with a loved one, or set off on an exciting adventure with friends, trains and train stations are quite magical. Here are some of my favourite train routes from around the world...
Harzer Schmalspurbahnen (HSB), Germany
West Highland Railway (The real Hogwart's Express), UK
Glacier Express, Switzerland
Train under cherry blossoms, Alishan Forest Taiwan and Segawa Valley Japan
