i just had to go for a work and do some shit for work anyway, was walking past the Swisshotel on market street heard a massive bang from the monorail thought wtf was that, turn around one of the wheels had snapped of the monorail and there was a tour bus dropping off tourists to the hotel. The wheel that fell of clocked one of the workers on the head in the jaw region probably knocked out a couple of teeth and he was spitting blood out everywhere, i mean what are the chances of this happening.
By the time i got back they had an ambo there to treat him.
There wheels are about the size maybe a bit bigger than the ones on a garbage wheelie bin but looked to be solid metal, with rubber round the outside
