My cheapest ever flight was either £9.99 (or €9.99?) for a one way from Berlin to London Gatwick, the train onward from Gatwick to Havant cost twice that.
I've also had round-trip air tickets on the same route for about 300.
Also, at the start of December I had a week long trip to the UK, and my flight back from Stansted was cancelled while I was on the runway and the first replacement flight Ryanair's website listed was a week later, so (after further nonsense I will not repeat here) I took the train to Portsmouth, the ferry to Cean, and then a train to Berlin. The combined cost of all of those and the hotel in Cean was about a third the cost of any earlier direct flight from any airline listed on Skyscanner.
The EU seems hell bent on turning Europe in England for some reason.
France and Spain believes that High-Speed rail is basically an airline. They miss basic stuff like one line should connect to the other, and are bad in terms of connecting high speed rail the rest of the infrastructure.
German has political problem building out a rational designed overall network and is vastly under-funding lots of rail infrastructure projects that are total non-brainers. But because its all politics with little planning.
I am extremely pissed that Switzerland build a huge tunnel threw a mountain, only for Italy and Germany to basically do nothing. Everybody expected Italy to be behind, but Germany is still not done its part.
Switzerland on the other hand basically doesn't believe in high speed rail at all and that is kind of a problem if we ever want a real European high speed network that doesn't suck. Thankful some people are pushing for such a line. We basically need a line Genf-St.Gallen, and Basel to Lugano. And then connect those to the high speed lines of the nations around us.
Britain in the meanwhile is actually building high speed rail, but constantly trying to cut it down, and at the same time they are not connecting their net with Europe because of stupid immigration policies.
Belgium has the slowest high speed rail ever.
Netherlands and Germany can't seem to figure out basic East-West connections.
We have long way to go in Europe to actual get high speed rail correct.
Doing such a high speed lane would open up massive amount of capacity. More local trains, more regional trains and importantly more cargo trains.
Switzerland has a modal share of over 20% for rail, and if we want to boost that to 40%, then new high speed rail is a must.
> The non mountainous parts of the country are densely populated.
Switzerland is not even close to as populated as Southern England, and somehow they are building high speed rail. And the British aren't exactly known to be great infrastructure builders.
> Besides if not all trains on the network can go this fast you need to increase the interval between trains which you obviously don't want to.
You would use special high speed trains on the new high speed lines and use all the other trains on the other lanes. Just as they will do on HS2.
