This map is downloaded from the site of Ceske drahy. You can find recent timetable there too.
And this is the map which was here before. This map is little bit older, but you can find there tracks, on which a passenger freight is no longer carried on (for example track number 242: Dobronin - Polna). But it is still newer than this one from the year 1949.
Railroad maps of some other countries are here:
Belgium, China, Croatia, Republic of South Africa, Crimea, Latvia, Hungary, Germany, Portugal, Slovakia, Scotland.
