Does the underground cause pollution?
Inhalation of particulate pollution is associated with health risks including heart disease, strokes, lung cancer and chronic obstructive pulmonary disease. However, fine particles found underground differ from those found above ground, with the health effects less clear.

Are underground trains good for the environment?
Reason 1: An underground train would be great for the environment because it would eliminate air pollution. When any vehicle is driving on the streets it is releasing exhaust into the air we breathe. The vehicle in question (underground) would not cause this problem.
Why does the underground make so much noise?
The vibration caused when metal train wheels roll over metal tracks is carried through the tunnel and the ground around it to nearby buildings. The walls and floors of these buildings can amplify the noise. We monitor reported noise levels across the Tube network.
