What you see on these images as well is, that MF does not show rails of tram- or subway. This may be irritatitng, because such rails very often simplifies orientation, when you are at the location or when you search for a location on a map and you assume, that there is a tram stop (such als Germany, Erfurt, Am Urbicher Kreuz, where I had to drop someone on this tram stop last weekend). Those data are sometimes essential for pedestrian navigation.
