Hilton’s photo essay Bulgaria’s Last Narrow Gauge Train was featured in The New York Times “World Through A Lens”. An elderly Bulgarian dairy farmer is among the small group of people who rely on this historic train to get her goods to market. For nearly a century, this little train has cross the Rhodope mountains, connecting people and livelihoods across a series of remote mountain villages and towns. But the trainline is losing money and is in constant danger of being shut down, like numerous narrow gauge lines taken out of service in recent years . But hope has come from the efforts of a couple of young train enthusiasts who have devoted themselves to saving the trainline, which they consider a national treasure.
