This network graph has as its nodes points at which passengers would embark or disembark trains or boats on long journeys from London to various European destinations, as advised by the table of quickest routes in the index of Cook's Continental Time Table. One can trace the quickest journey back to London by clicking on any destination and following the arrows. This graph shows how British travellers to Europe did so overwhelmingly via a small number of places -- most notably Paris but also Cologne and Basel ("Bale" in the time table). Thus we can see that France, and the French state as encountered in Paris, was very familiar to British travellers. And while the Rhineland was familiar, Prussia and Berlin were distant and passed through relatively seldom.
This map shows most of the data points on the network graph on a modern map of Europe, with the size and colour of the dots indicating distance in hours from London as indicated in Cook's Time Table. Regrettably, to allow Google's geotagging feature to work, it uses modern place names and country names. Those points with more than one dot represent multiple routes taking longer or shorter amounts of time. This kind of scale gives one a more meaningful sense of how far different places in Europe were from London, and thus perhaps how distant and foreign they seemed to British people before the First World War.
