Is Deutsche Bahn a successful privately held passenger rail company?

Question

In the US a large network like DB being run privately would seem far fetched.

Answer 1

Deutsche Bahn is German State Railways; they are in the process of being partly privatised and are allowed by the German government to engage in the rail business in countries like Britain where the railways are operated by private companies. Currently in Britain Deutsche Bahn owns the rail freight operator EWS and the passenger rail operator

Chiltern Railways that runs trains between London Marylebone, Aylesbury, High Wycombe, Banbury, Birmingham and Stratford Upon Avon. Chiltern is one of our most respected train operators currently operating at around a 96% punctuality rate; it has also initiated all sorts of cheap fare offers like one way fares from London to Birmingham
