Railfans are more 19th century than 21st century, and their fascination with all things rail-related is at an all-time high. They line up along train tracks and thrill to the rush of engines and freight cars roaring past. They explore unused rail lines, tunnels and stations. Some even collect timetables or strive to ride every line in a railroad network. Likewise, bygone-era canals seem to inspire similar fascination and devotion. Enthusiasts around the world (called gongoozlers in Great Britain) are drawn to canal boats, towpaths, locks and collecting canal-related postcards and paintings.
