All types of generated electricity from various types of sources (e.g. nuclear, thermal, hydro, wind, photovoltaic or other renewable sources) to be distributed to consumers through the grid or consumed locally. It is measured by the calorific value of electricity (3.6 TJ/GWh).

Line with one or more electrified running tracks. Sections of lines adjacent to stations that are electrified only to permit shunting and not electrified as far as the next stations are to be counted as non-electrified lines.

Track provided with an overhead catenary or a conductor rail to permit electric traction. The following types of electric current are in use:
- AC 25 000 Volts, 50 Hz

Emissions of CO, NOx, NMVOCs, PM10, PM2.5 and SOX can be grouped into acidifying substances, particulates and ozone precursors. Transport contributes significantly to emissions of NOX, NMVOCs, PM and CO. NOX contributes to acidification, formation of ground level ozone and particulate formation.• PM2.5: particulate matter with aerodynamic diameter of 2.5 μm or less;• PM10: particulate matter with aerodynamic diameter of 10 μm or less;• NMVOCs: non-methane volatile organic compounds;• SOX: sulphur oxides;• NOX: nitrogen oxides;• CO: carbon monoxide.
