The safety rules HAVE been reviewed.
Some stuff has been dropped - such as the needs for seperate power cars and the ability to split the train - but running two Velaros together would affect the economics of the service - and DB have no intention of running it just to lose money.
cool, so they're your photos I found, sweet. Really top work with all of them. So it looks like an all clear for through the tunnel then!
Sure they wouldn't want to lose money, however, if as Gordon says, an ICE from Frankfurt joining an ICE from Amsterdam at brussels would probably make the money.
I guess it would depend where they pick people up from and how they would do the security stuff because for Eurostar you have to go through the baggage scanning.
Every Eurostar I have been on from Brussels has been packed to the rafters, if there is another service added to that pattern, perhaps they might need to add the second one anyway
But i am no economics expert
