@poVoq @Vittelius i life near of one of the low speed halts. Lets say I want to go to Sylt. I take a low speed train to an high speed stop and then use the train to go to sylt. from the local trainstation to sylt i have 3 stops and in 7 hours im there. Coexisting is possible.
@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)
