Geography tends to overlook trains. Cars, airplanes, and city-level mass transit are the topics of choice for those who study transportation geography and the geography of human connectivity
Now; however, there are nice treats for those who enjoy trains and geography. Because of neogeography one can now follow live maps of Amtrak and National Rail trains. Amtrak Status Maps website looks old but can still do the trick. On the side bar there is a map of the United States divided into regions. Just click the region one is interested in and a map will load showing trains and whether they are on time or delayed. If one clicks the train number a time table will appear showing all the data a train fan could enjoy. Meanwhile The Vaguely live map of trains in the United Kingdom uses a Google Maps mashup to depict data. One can select the station of interest and see all the other stations along the line and also watch the trains move slowly on the map. The time when the train is due at the next station is displayed and many of the trains have the option to view their information board to see how on time the train is running.
