The Bulgarian government through its Privatization Agency has embarked Friday on a new campaign to privatize troubled Bulgarian State Railways BDZ's profit-making Freight Services unit to make up for losses from its passenger unit.

The announcement, posted on the Agency's site, informs that only strategic and financial investors will be allowed to bid.

Strategic investors must have experience in freight railways transport in the last five years, a license to carry out such services, a safety certificate, and minimum annual revenue of EUR 100 M in the last three years.
