From the particularly good blog World War II Today,
the entry for 14 October 1940:

They had gone to the Tubes for safety, instead they found worse than
bombs, they found the unknown, terror. Women and children, small babes
in arms, locked beneath the ground. I can only visualize their
feelings, I can only write how it has been told to me, but it must
have been Hell. On top of this there came a cloud of gas. People not
killed outright were suffocated, the rest drowned, drowned like rats
in a cage.

I lived bear Balham for a few years in the late 1970s and a good few
locals had vivid stories of that night. And it wasn't just the tube
that suffered. Apart from the tramway, in the blackout a bus didn't
manage to mind the gap

Holes in the ground are often measured in DDBs (double decker buses)...
they don't usually use an actual bus to measure it though.

There is a memorial on the wall at the moment which does mot mention numbers.
