POTENTIAL RECYCLABILITY AND RECOVERABILITY With the development of the Prima II locomotive, Alstom sets standards for a sustainable product development. A recycling rate of 93% has been calculated according to ISO 22628. The recovery rate amounts to 95 %.

This calculation of energy consumption has been done in France, between Calais and Arras. It is a 133km line for which the maximum ramp is 12‰ during few kilometers. The assumptions for the simulation reflects the profile lines of major European corridors. The catenary voltage chosen for these simulations is the 25kV - 50 Hz. This is a catenary voltage representative for today most European routes. The results below are derived from a simulation. Each module of the drivetrain simulated accurately represents the subsystems of the real locomotive. The profile mission is very important, therefore, the potential energy of 0,98 Wh/t/km due to the difference in elevation between the start and finish (48 meters) will correct the result.

Simulation conditions

 The train consists of a locomotive ALSTOM PRIMA EL2 BoBo hauling wagons of transport combined type. The total mass of the train is 1590 tons. The configuration of the simulated train, due to its weight, represents a classic freight train. No "smart" driving to reduce the consumption of energy is implemented in these simulations. A 2 minutes stop will be made on the course Calais-Arras. This stop can be closer to the real conditions of transport of goods.

Results & Conclusion

 The average score of 12.5 Wh/t/km, give us an idea of the energy performance of the locomotive PRIMA II. This value is highly dependent on the locomotive’s terms of uses, for example - A driving style more or less flexible - A high maximum speed, dependent on the travel time - The option of regenerative braking energy It can change the results in one way or the other. The 12.5 Wh/t/km value is therefore a representation of the energy consumption for consistent configuration settings.

Noise emissions

 The noise emissions of the Prima II have been measured according to Noise TSI 2011/229/EU. The external noise level has been measured at a distance of 7.5 m from the track centre and 1.2 m above the top of the rail and the internal noise at the centre of the cab, and at the train driver’s ear height (1,60m). The table below shows further result: External Noise dB(A) Stationary sound pressure level 62 Acceleration sound pressure level 84 Constant speed sound pressure level (measured at 140km/h and normalized at 80km/h) 85 Internal Noise dB(A) Constant speed sound pressure level at 140km/h 74
