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.
