In Japan, wild animals are increasing in number in urban areas year by year. For instance, I recently found a wild Japanese raccoon dog on a railway track near my home. While I was taking pictures of trains on the Keio-Inokashira line, he (or she) appeared from a drain along the track, and enjoyed walking around. As I posted before, Japanese raccoon dog, also known as tanuki, is a canid animal inhabiting only in the Far East. Japanese people have a strong affinity for this animal, as we often see them in folk tales, in which they often shape-change as a messenger of God. A railway track might be a very safe place for wild animals, as it's beyond limits except for railway employees. In other words, railway tracks will be the best routes for wild animals to extend their habitations. Railways are not only for trains but also for wild animals!
Incidentally, the Keio-Inokashira line is a short urban commuter route penetrating residential areas in the western part of Tokyo Metropolis. There are 17 stations over a total operating length of 12.7 kilometers. The EMU 1000 series is a sole model being operated on the line. 29 sets, 145 cars in total, were introduced from 1996 to 2010. One of the features of this EMU is that each train set shows a different color on the front mask and the side lines. Those are orange-beige (see the photo below), ivory white, salmon-pink, light-green, lilac, light-blue and blue-green ... the seven rainbow colors.
