importance today. Through their daily activities people pollute water,

air, soil. If we do not stop these activities the damage may become irreversible.

most dangerous sources of pollution of the Earth is

railway transport. Now railway pollution accounts for 9% of all harmful substances. Every year railway enterprises throw into the atmosphere

nearly 40 thousand tons of harmful substances.

much harmful waste into air as 40 or 50

cars.

of harmful substances are released into the environment, including

coal containing a large number of heavy metals and hydrocarbons.

The most dangerous and uncomfortable impact of transport on a person is considered to be pollution by hydrocarbons.

organic and inorganic origin:

pollution in human settlements

the path passenger cars pour up to 200 m³

of sewage, containing pathogenic microorganisms

and emits up to 12 tons of dry waste. This leads to contamination of the railroad track and the environment.

the established migration routes of living organisms, violate their

development and even lead to the destruction of entire communities and species.

transport is a great source of noise. As we

know noise is a special kind of environment pollution. The most efficient way for the

reduction of rail noise
is the proper track layout and reduction
of noise of the diesel engine.

reduced in origin, then the solution is in noise

barriers. They should be placed as close as possible

to the track and have a height no less than 2 meters. In addition noise barriers should be made of special absorbing materials for additional noise reduction.

total energy in the world community. Railway have the

lowest unit energy consumption compared to other transport modes. Besides, in electrified railways, energy can come from clean forms such as hydro power stations rather than from oil, especially now when the oil reserves are becoming exhaustible.

Sayano-Shushenskaya hydroelectric power station is the largest one in Russia

rail transport than for other transport modes and specifically

fifty times less than for road transport.
Land occupation in the world for:
– road transport 68 937 575 км
– rail transport 1 370 782 км
