Just watched a piece on Ch4 News where Deutsche Bahn claimed that trains could run from London St Pancras to Frankfurt in under four hours.
Would that be a viable alternative to a flight from any London airport?

I notice the Metro article states a journey time of five hours, so unsure where Ch4 News got the "under four hours" from.
