You lost me at ‘single model of 300km/h train that can make it here’
Meanwhile here in Australia our “fast rail” trains go 160km/h. Unless it’s over 32 degrees, then they slow down. And if it hits 36 degrees they slow down even more (90km/h)
I suppose it's difficult to make that mistake because plane tickets are to cities, not countries as a whole.
As a real story, I knew a guy who had a B&B near a beach called San Francisco, in Spain, and he regularly had to cancel bookings from people who thought it was in the US city of the same name, though :)
