Cosan is expected to take the Rumo-ALL merger for analysis by the Administrative Council for Economic Defense (Cade) anti-trust court in coming days. Until the body makes a decision, the companies must operate separately, even if the deal is approved at a shareholder meeting. 

With the merger, the resulting company will carry less sugar and more of other commodities, which offer more advantageous freight (by using a larger stretch of ALL's rail network). Valor has learned that the reduction in the transport of sugar may begin soon, even before Cade’s decision. 

The deal under discussion is part of transition rules for the coexistence of the companies in an attempt to smooth the billion-real dispute over the contract signed in 2009.
