UPDATE 1-Brazil's Vale reaches $1.8 bln railway concessions deal

Adds details of the agreement in paragraphs 3-4

SAO PAULO, Dec 30 (Reuters) - Brazilian miner Vale VALE3.SA has reached an agreement with local authorities to pay up to some 11 billion reais ($1.78 billion) to renegotiate two railway concession contracts, the firm announced in a securities filing on Monday.

Brazil's government has been aiming to remove discounts given to rail companies by the previous administration when some received early contract renewals.

In its filing, Vale noted that it has reached agreement on general terms with the government and land transport regulator ANTT for the renegotiation of the Carajas and Vitoria a Minas railways concessions, which in 2020 were extended through 2057.

The company added that the agreement still awaits additional approvals, and will lead to an increase of 1.7 billion reais in its provisions related to railways concessions.
