The development of new legislation and standards has an important impact on the design of new rolling stock. In 2015, a new full revision of the TSI NOI (Technical Specification of Interoperability NOIse) will be in force, merging the requirements for conventional rail and high-speed rolling stock and defining new limit levels. The so called simplified method is a very important change that was fully introduced in the limited revision of the TSI NOI in 2011 [2011/229/EU]. In the long term, the ambition is to partially replace physical TSI testing by so called virtual testing, in which calculated results are used as a decision basis. In the EU, fulfilling the TSI NOI is mandatory for vehicles to be allowed to run on the Trans European Transport Network infrastructure. However the application of the TSI is becoming more widespread as customer contractual requirements from other parts of the world like Asia, Australia and Africa are increasingly referring to the TSI NOI. Additionally, although the TSI NOI does not apply to vehicles such as metros or those circulating on functionally separated networks, these now often explicitly refer to the TSI NOI in the train technical specification. In the paper, we give examples of how the TSI NOI has been applied in vehicle projects in different European and non-European countries. Also, the benefits and procedure for applying the simplified method will be described for a recent European vehicle project and some initial results of activities supporting virtual testing from the FP7 project Acoutrain is illustrated. The interaction between the research needs for noise and vibration and the new 920 million euros European Programme for Rail R&D, Shift2Rail, will be presented and an outline of research strategies in Shift2Rail will be included.
