Just what your ordered? http://www.openhistoricalmap.org/ http://www.openhistoricalmap.org/ http://wiki.openstreetmap.org/wiki/Open_Historical_Map http://wiki.openstreetmap.org/wiki/Open_Historical_Map Given that it is all based on the OSM database, I'd imagine OpenHistoricalMap would already cover historical railways? There is a renderer for the "railway" aspect of the OSM database (openrailwaymap.org), one for the "historic" aspect (openhistoricalmap.org), so it's a matter of programming for the railway map renderer to include the history aspect. --- Edit: Just notice the following note about OHM: "As opposed to other projects such as OpenSeaMap, OHM makes use of its own database independent of OSM." A pity, as this means ORM won't automatically pick up history. OSM does have a "4D" proposal to include time: http://wiki.openstreetmap.org/wiki/OSM-4D http://wiki.openstreetmap.org/wiki/OSM-4D , but it seems that it is not yet active.
