In the meantime Ken Livingstone will be meeting London Underground staff today in his usual weekly meeting with them. On the agenda definitely will be the fact that some drivers have been refusing to take out tube trains as they had safety concerns.
RMT union leader Bob Crow said staff had expected the entire Tube network to be shut down yesterday, which is what happened on July the 7th following the earlier bombings.
"At the emergency meeting we were told that lines apparently unaffected by the attacks should continue running.
"We will be discussing these issues further when we meet the Mayor, but the RMT has made it quite clear that any LU worker who refuses to work in these circumstances on the grounds of safety will have the complete support of the union."
Mr Crow paid tribute to the "professionalism and commitment" of LU workers who helped to evacuate Tube stations. See The Evening Standard's site for the full story.
The announcement drew complaints from civil liberties advocates in a city where more than four million passengers ride the subway on an average weekday (by comparison about three million use the London Underground each day). The New York subway has more than 468 stations.
However, according to The New York Times most commuters grudgingly accept the inconvenience and I'm sure the same would happen in London if a random search was introduced. As the article says:
"For some, the prospect of the police stopping people randomly, peering into their bags and waving them on seemed to be just another nuisance. In a system where the up escalator so often seems to be broken, where trains always seem to run late when the appointment is most urgent and where the rats seem determined to jump from track bed to platform, how much difference could an occasional bag check make?".......
"Many riders were more reserved in their judgments, and less inclined to question the motives of the police, but were clearly not convinced that a cunning terrorist could be stopped by random baggage checks. The police made clear yesterday that no one would be required to submit to the inspections, and people could simply decide not to enter the subway."
