Historically it is a very special machine for our railroad because it was the first steam locomotive to offer services in this branch and also because it was manufactured entirely in our country, more precisely in the workshops specially established in Carupa, province of Buenos Aires, between february to november 1994. The original name was Nora, in honor of the original owner´s wife, but in 2007 it was decided to make a series of technical modifications and was renamed in homage to the Argentine Engineer Livio Dante Porta, specialist in steam locomotives, world-renowned. Technically it is an articulated locomotive Beyer-Garratt 0-4-0 + 0-4-0. The weighs approximately 10 tons and its engine has a power of 120 HP.
The work carried out by Tranex Turismo S.A. in its Carupá workshops included the construction of each components, reflecting Argentina's ingenuity and capacity in the integral development of steam locomotives. The model commemorates the British engineer Herbert William Garratt whose patent was bought by the English company Beyer Peacock and built the first steam locomotive of its kind in Manchester during the year 1909. Different railroads manufactured similar ones in Liniers, Escalada, Junín and Tafí Viejo, among others, that usually were great modifications of previous models or assembly of imported pieces.
