loud and causes sparks. The problem is replacing the aging track system would probably cost billions. At least the train cars are new and tell you
what time it is
On the London Underground the brakes are asbestos lined. as a result there's a fair amount of asbestos in the dust down there.
The Underground also has it's own breed of mosquito, found nowhere else in the world. Apparently they're believed to have descended from Mosquitos
which collonised the tunnels a few hundred years ago during the building of the network.
