BUENOS AIRES, June 11 (Reuters) - Grupo Mexico Transportes USA (GMXT) has reached a strategic agreement with the U.S. railway technology provider Wabtec to participate in the bidding process for the Argentine firm Belgrano Cargas y Logistica (BCYL), a source familiar with the matter told Reuters on Thursday.

Argentina in the coming days plans to publish the tender documents for the privatization of BCYL, which operates the country's three largest freight train lines. The company is aiming to renew its aging rail network to improve logistics for the agricultural, mining, and energy sectors.
