In 1961 the Government of Argentina led by President Arturo Frondizi closed the B. Mitre-Delta branch due to the low number of passengers carried and high maintenance costs.

[2] In 1990 plans were formulated for the reopening of the line and with the railways being privatised in 1992, the Tren de la Costa company (part of Sociedad Comercial del Plata, controlled by local businessman Santiago Soldati) was formed to take over the concession for the service.

Public services and related commercial operations began in April 1995, and the maiden ride was shared by Soldati, company and government officials, and President Carlos Menem.

Mitre branch, the new Maipú-Delta service was a light rail system, using articulated cars acquired from Spanish company Construcciones y Auxiliar de Ferrocarriles (CAF).

During the first years of service, the branch carried an average of 100,000 passengers (on weekends) due to it having been conceived as a tourist train, with Maipú, Libertador and San Isidro as its main commercial centres.

Beside the Delta terminus, a new amusement park, Parque de la Costa was built, advertised as the largest in South America.

Delta station serves the Parque de la Costa, an amusement park, as well as Tigre's other important tourist attractions including the Trillenium Casino, a crafts fair, riverside restaurants and boat trips.
