The wonder of the night train: headlamps ablaze, passengers boarding after sunset and leaving before sunrise, slipping in and out of compartments unseen. For Monisha Rajesh, the singular thrill of sleeper trains inspired a new journey around the world – one filled with moonlit landscapes, cosy compartments and quirky companions.From Austria’s Nightjet to Scotland’s Caledonian Sleeper and Finland’s Santa Claus Express, Rajesh invites us on a multi-year adventure aboard the world’s most wondrous night trains. Along the way she samples reindeer stew on the night-train to Norway, sips on pisco sours while riding the Belmond Andean Explorer to the shores of Lake Titicaca – and considers a game of cricket down a carriage on the Shalimar Express.A decade ago night trains were giving way to budget airlines and high-speed rail. But as people search for slower and more environmentally friendly ways to travel, night trains are in the midst of a renaissance. By turns romantic and hilarious, Moonlight Express brings us along for the ride – and drops us back at the platform before sunrise.
