EU member states were able to separate the provision of transport services and the management of the infrastructure by the Single European Railway Directive 2012. Usually, national railway companies were split to separate divisions or independent companies for infrastructure, passenger and freight operations. The passenger operations may be further divided to long-distance and regional services, because regional services often operate under public service obligations (which subsidise unprofitable but socially desirable routes), while long-distance services usually operate without subsidies.
