At the forefront of innovation and development in the rail world, the Southern Railway was the only main-line railway to embrace electrification wholeheartedly, creating what was at the time the world's largest electric suburban network. It was also the only railway to use passenger train ferries, allowing its sleeping car service between London and Paris to operate as a true through service, and its `Golden Arrow' all-Pullman day express even had its own luxury Channel ferry. These achievements would have been noteworthy at any time, but were set against the challenging background of worldwide depression. With the aid of stunning colour photographs, The Southern Railway Story explores this remarkable passenger-traffic-driven railway from its commuter trains, via its international express railway, to its role as a holiday railway serving many of the most popular seaside resorts.
