A post on the Guardian UK website:

Maybe it is too early to raise such a matter, but has the question been raised anywhere why the tube sytem was still operating at the time of the third bombing, 21 minutes following the second bombing and 26 minutes following the first bombing? Also, why the london public transport system (buses) was still operating nearly an hour after the first bombing, and half an hour after the third bombing? I cannot immagine that any stort of anti-terrorism plan for London public transport, properly executed would allow this to happen with such tragic consequences.

Anyone else seen any other questions starting to emerge?
