The British railway system was one of the first national systems in the world; so, it is not surprising that they also have the largest railroad museum in the world. Offering a number of online exhibits, their site is an excellent resource for anyone, young and old, hoping to learn more about the history of railroads in Britain. For starters, users may want to look at the Frequently Asked Questions section, where the Museum's experts answer a number of queries, such as "How does a steam locomotive work?" and "What is the world's heaviest train?" From there, users will want to take a virtual tour of the Museum by navigating to the Panoramas section, where they will have the ability to look around the Museum's Great Hall, where legendary British locomotives are kept, as well as viewing the interior of the Mallard, the world's fastest steam locomotive. The digital exhibits are located in the Exhibits section, which includes presentations combining short essays and visual materials on nine different themes, including "The History of Railway Photography;" "Railway Posters;" and "North by Northwest," which highlights recent photographic work taken along rail routes in Scotland.
