By the early 20th century, as the railroad became a vital means of moving people and goods, trains and locomotives became the focus of some of the world’s finest mechanical engineers and industrial designers. From this increased attention arose perhaps the most elegant land-based form of transportation in human history: the streamlined train. Relive their glory through magnificent photographs of these cars, which show both their elegant interiors and their graceful shapes speeding across the countryside. Here are the ever-more luxurious rolling accommodations for the discriminating traveler, with increasingly spacious sleeper cars and dining rooms that came to resemble those in four-star restaurants. Written and researched by a team of veteran transportation historians and illustrated with more than 175 black-and-white and full-color pictures, this tribute honors not only the dazzling passenger cars, but also the legendary designers, and presents the gorgeous promotional brochures and posters used to entice passengers.
