Tasselli began his involvement in the railway sector in 2000. His firm Metropolitano is the concessionaire for the railway lines Belgrano south and San Martin. It was also the concessionaire for the Roca line, which was returned to the state “in the midst of allegations of deficiencies in the services provided.” As of 2004, Metropolitano was billing $650 million a year and employed 12,000 people. In July of that year, he was engaged in a “full legal dispute with the government over the decision to rescind the contract to operate the San Martin branch” as well. During that dispute, he said that he was being “persecuted” by Transportation Secretary Ricardo Jaime.
