I have attempted to identify and map the railroads Twain rode on during his American Vandals tour. This is tricky because the lines he took are rarely identified. Another problem is the temporal aspect. They all change their names, lease themselves or sell themselves. Most of these lines are from the USGS quads, which may be decades later than Twain's travels and are often divisions within a larger railroad, ie the Pennsylvania or the Boston & Maine, etc.. The mapped lines are clickable as are the cities.
