@ManInTheMiddle @Vittelius the rail gauge is mostly one size already: 1435 mm, only spain and portugal are missing.
The train control systems must be replaced by etcs, this is an european regulation.
The electrification is the only Problem that needs to be solved. We have many different power systems that use highly different voltages. (750V to 25 kV)
