Shimogoinden-bashi (Train Museum)

"An overpass bridge located close to the North Exit of JR Nippori Station which connects the station's east and west sides. A balcony is situated in the center of the bridge, and from here you can look down on trains passing directly below. 14 lines, including JR Shinkansen trains, limited express trains, and the Keisei Main Line pass through here, and because you can watch some 2,500 trains spanning around 20 models coming and going from here on any given day, it has become nicknamed the ""Train Museum."" A popular destination for train-lovers of all ages, the bridge is free to use and there are also informational panels with pictures of the trains you can see here."
