Yes there are a lot more buses.

With a lower number of passengers per bus than a tube train.

They also have far more unpredictable events to deal with.

At much lower speeds (average 11 mpg in the City or summat) and with
much easier access to the emergency services than when in an
underground tunnel.


Any idea how may PAX a tube train carries at all?..

Does it compare with 10000+ at a match?

But it's all down to the 'typical risk', not some worse case
situation.

Any 'accident' in a tube train is likely (not 'unlikely') to injure
more people than the same in any single bus, simply because of the
typical speeds and number of passengers.

I agree though that the likelihood of a tube train crashing into a low
bridge because it's go off route or hitting another vehicle (big
enough to cause *it* issues) are probably less. ;-)
