Trees don't fall in good weather. I suspect the branch got caught between
the bus and the tree-protection rail and the branch/tree was pulled over

Not the whole tree, just a branch.

by the bus. This may lead to all such rails being replaced by a solid
protruberence.

If that had happened the bus would have already partially passed
underneath when it started pulling the branch down which then surely
would have fallen onto the roof , not clobbered the front?

One bus (or other high vehicle) could have dislodged it, and a bus
behind hit it. This is pure speculation, trying to fit the visible
evidence to the laws of physics.
