Requirements on locomotives and passenger units

New locomotives and passenger units shall normally be authorised according "The new approach". This mean that the vehicles shall fulfil the requirements according relevant TSIs (European Technical Specifications for Interoperability) and national requirements regarding open points and specific cases in the TSIs. The Swedish Transport Agency (the national safety authority of Sweden) also applies The new approach in the authorisation process. This means that a notified body assesses the vehicles fulfilment of the TSI requirements.

Valid TSIs

New locomotives and passenger units shall normally fulfil the following TSIs for the authorisation:

Also upgrading and renewal of authorised vehicles shall fulfil requirements of these TSIs, however only regarding the modified functions.

There are also old TSIs which may be applied during a transition phase e.g. High speed TSI Rolling stock (2008/232/EG) and Conventional Rail TSI Locomotives and Passenger units (2011/291/EU). The Swedish Transport Agency has access to these TSIs .

The Swedish Transport Agency and the European Rail Agency (ERA) have issued a number of technical documents and guide lines to facilitate the application of the TSIs and authorisation of rail vehicles.. Below you find the guidelines regarding locomotives and passenger units.

When application for authorisation of a vehicle (or a series of vehicles) the applicant shall engage one or more notified bodies. These notified bodies shall assess the vehicle and issue a certificate of compliance to the TSI(-s). The applicant should also send an application to The Swedish Transport Agency at the start of the process to get information on the applicable national requirements for the authorisation. In case of an upgrading or renewal The Swedish Transport Agency shall decide which functions have to be assessed for the new authorisation.

National requirements, open points and specific cases

TSI-compliant locomotives and passenger units shall fulfil the TSI-requirements and national requirements regarding open points and specific cases in the relevant TSIs. Some new TSIs went into force 1 January 2015, they are applicable on the whole European railway network.

In the TSIs there are some specific cases which are necessary for the interoperability vehicle – infrastructure including the Nordic winter climate conditions. There are also open points in the TSI where there are no requirements given in the TSIs. New, upgraded and renewed vehicles shall be assessed according to national requirements regarding specific cases and open points.

There are only high level requirements set in the Swedish regulations on rail vehicles. The Swedish Transport Agency has issued guidelines with accepted technical solutions for different functions of a vehicle to facilitate for the applicant. In the TSI Locomotives and passenger units (EU nr 1302/2014) most of these functions are set. For new, upgraded and renewed vehicles the TSI requirements should apply. Our guidelines are only applicable for specific cases and open points. The guidelines are applicable for imported vehicles which need an additional authorisation for operation in Sweden.

Guidelines for locomotives and passenger units

The following guidelines states accepted technical solutions for authorisation of a locomotive or a passenger unit (some are only available in Swedish):

In the TSI Locomotives and passenger units there is a specific case for Sweden saying that the vehicles shall be designed for operation in the Nordic winter conditions to get an authorisation without operational restrictions. The applicant shall demonstrate the safety and reliability for operation in severe winter conditions. Hence The Swedish Transport Agency require experience operation to issue a "permanent" authorisation without operational restrictions.

To operate a rail vehicle on the Öresund link the vehicle has to be authorised both in Sweden and Denmark.

Cross acceptance of "imported" vehicles

The national requirements are valid for additional authorisations of vehicles with an authorisation in another EU+-state. Transportstyrelsen applies cross acceptance by additional authorisation, which means we accept A-classified functions without further assessment of the these functions. Only functions with divergent requirements for operation in Sweden shall be assessed by
authorisation of "imported" vehicles (B- and C-points in RDD). Correspondingly vehicles authorised for Sweden shall get additional authorisation according to cross acceptance when imported to other countries.

Sweden has, together with Denmark, Finland, Germany and Norway, signed a Memorandum of Understanding (MoU), that will facilitate the process of additional authorisation of railway vehicles.

Requirements for installation of train protection and train radio systems

New railway vehicles with a driving cab shall normally have the train protection system ETCS-STM installed. See requirement on the page "Requirements on onboard Command Control and Signalling.

All vehicles with a drivers cab shall have a GSM-R train radio installed. From 1 Juli 2016 this train radio has to be protected from disturbances from other radio systems.
