As far as I am aware, only selected operations are franchised in Germany, mainly by the Länder, although some are quite large. Certainly, I have never seen mention of franchising the IC services, although there is some timid open access competition.
The background to the German structure is quite involved. In the 'Basic Law', the
Grundgesetz, which was written after the War when the Federal Republic was being set up, the requirement was that the provision of rail services was a matter for the
Bund, the Federal government. This remained the case for many years and many railway staff, including drivers, were classified as
Beamter, essentially senior grade civil servants - although there is no direct comparison here. This meant that they could not strike, could not be laid off (except for serious offences such as having their hand in the till) and were security checked to ensure that they were not communists or sympathisers. The costs of running the system, the loss of traffic to the roads and the need to make changes meant that attempts were made to change the structure. The status of
Beamter was removed for many staff in the days of Chancellor Schmidt in the late 1970s in an effort to make the organisation more flexible.
Following the re-union of Germany there was a reform of the now united East and West railway administrations in 1996. This reserved long distance traffic,
Fernverkehr, for the Bund and made the Länder responsible for regional traffic. The German Constitution, the modern equivalent of the
Grundgesetz, still reserves long distance traffic as a matter for the Bund. This is why there have not been any attempts yet to offer it to third parties to run.
The Länder may buy in transport services in their area, which is why companies do supply some of the trains. However these are operating contracts only - for so many train-kilometers per year - and do not include any revenue risk.
The problem which exists - and it is being debated in Germany now - is that DBAG also charges for track access and there are strong suspicions that it rigs the charges and takes legal action in order to benefit its own train operations. See for example the latest case for the S-Bahn in Nurnberg. There is no independent economic regulator in the German system and as a result the private sector - even the private freight operators of which there are many - claim that they are being discriminated against by DBAG.
This will run and run. But the point is the German structure, legal, political and financial is very different from that pertaining here.
