James Farrar ) gurgled happily, sounding much like
they were saying :

AFAIK it's a straighforward 17t weight limit

So Bendis can't use Tower Bridge?

How much does a bendi weigh?

About 17t - empty.
ULW is written on the side of all buses.

RMs are about 8t, modern double-deckers about 12t.

Bendies are about 16.5 tonnes so would just get in within the limit as
long as they were nearly empty. I reckon half a tonne of people is about
6 or 7.

Isn't it unladen weights that determine weight limits?

No. Normally weight restrictions are based on MAM - Maximum Authorised
Mass.
