Greece's privatization fund on Wednesday announced the launch of a new international tender to privatize the country's railways operator TrainOSE.

"The Hellenic Republic Asset Development Fund (HRADF)'s board of directors decided the launch of a new tender for the sale of 100 percent of shares of TrainOSE in order to attract bigger interest by investors," the agency said in a statement.

The fund annulled the previous tender as none of the companies which had participated in the final stage (the French SNCF, the Russian RZD and the Romanian GFR) submitted a binding offer for the purchase, while new candidates expressed interest, according to Greek national news agency AMNA.

Potential contenders can express their interest from Feb. 1 to April 26, 2016, according to the new announcement.

A week ago, the HRADF accepted China's COSCO's offer for the acquisition of the 67 percent stake in Piraeus port for 368.5 million euros (400 million U.S dollars).
