Gregory's ServerThere is also a lack of high-speed services connecting major cities across the block, especially east to west.
They're only just about to start an 8 hour daily direct high-speed service between Paris and Berlin*.
I ran into this during the NATS debacle in the UK last year and had to get back to the UK from Prague. There were no viable train options from Prague and I ended up flying to Paris via Munich and taking trains to Dieppe and then a ferry to the UK.
