evidence: It's not just the views that has travellers in awe. The train journey itself has become an Instagram sensation in recent years, with travel bloggers risking their lives to take photos of themselves hanging off the door as the train rumbles past rickety bridges (some of them have been criticised for their dramatic poses).
