@jon Wow, that's impressive. I misinterpreted "Eurostar" as trains connecting London to "Europe" (i.e. the old Eurostar label). Would the cross-channel connections also have more capacity if operated at max?

@jon Prices on Eurostar are just insane. Even for families it is often cheaper to fly than to go by train. Competition alone won't fix it though without extra infrastructure, no? You would know better, but my status is that there isn't more capacity through the channel tunnel than what they already do.
