Depending on the country, train lines face different and unique challenges. For the Nordland, it’s Norway’s mountainous terrain; for Italy’s Frecciarossa, and its domestic rival, the Italo, it’s complex logistics and a myriad of safety and security precautions. For the Indian Pacific? The trifling matter of crossing a 3,700 mile terrain where temperatures regularly soar past 100 degrees. What they all have in common is a range of innovative solutions to seemingly insurmountable problems, underpinned by a tireless dedication to their passengers.
