In Spain the high speed network is separate from the traditional network too. There is some inter connectivity to allow for high speed trains to call at traditional stations, but the high speed network is for high speed trains only.

Yeah, the planned Czech high speed trains (VRT) have the same gauge but are expected to be used by the high speed trains almost exclusively, with a limited number of normal-speed passenger trains and AFAIK no cargo traffic at all.
