Eisenbahn-Bundesamt
After a re-tender of operations for twelve years, operations of the services from 11 December 2011 were taken over by the DB Regio Hessen GmbH, a newly formed wholly owned subsidiary of DB Regio. The operation of Bombardier Talent 2 electric multiple units were intended to be used from the beginning of the contract, but were delayed by problems in obtaining certification for their operation from the Federal Railway Authority as on other routes.
