(1 Use phase emissions of electrict trains are zero
(2 The electric power generation efficiency used in the calculation of primary energy (55,8 %, factor 1,79) is derived by diving the total use of electricity in the year 2012 (85131GWh) by the use of energy in electricity production (152500GWh) in Finland
(3 The amount of electrical energy taken from the contact wire by the locomotives
