Abstract
Simulating the exterior noise levels created by the train equipment requires a good representation of the equipment integration, the noise propagation, the ground reflection and, for some cases, the diffraction in the different train surfaces. In the framework of the European project Shift2Rail program S2R-CFM-CCA-01-2019 Energy and Noise and Vibration, the state-of-the-art of the exterior noise of rolling stock vehicle simulation is being compared between railway manufacturers and operators and the advanced techniques proposed by the consortium Open Call project S2R-OC-CCA-01-2019 (TRANSIT https://transit-prj.eu). With respect to previous work done in the same direction (ACOUTRAIN https://cordis.europa.eu/project/id/284877/reporting/es, SILENCE http://www.silence-ip.org, FINE-1 https://projects.shift2rail.org/s2r_ipcc_n.aspx?p=FINE%201), the focus of the work is on the train integration effects of equipment in a rolling stock.

Notes
- 1.
Equipment used in rolling-stock products to prepare the electrical signal in terms of voltage (V), current (A) and phase to the train auxiliary equipment working at medium voltage (i.e. Heating, Ventilation and Air Conditioning Unit) and low voltage (i.e. batteries).
- 2.
Power here is defined as the product of the voltage (V) by the current (I).
- 3.
It was not possible to increase the load more than 2 kW on the train without switching on the HVAC and with only two vehicles presents from the whole train.
- 4.
For example, when simulating the left side of the train, the monopole on the right is deactivated.
- 5.
Main contributing frequencies are defined as the third octave bands with sound pressure level that lies between the overall global noise measured and 6 dB below.
