On 11 November 1888, a line 70 km long between Trelew and the quay in Puerto Madryn was opened. It included the first telephone line of the region. Journey time (that were made on horseback) reduced from 20 hours to only 2 hours in train. From Trelew the line was extended 50 km to Gaiman on 31 December 1908 and from there to Dolavon on 12 October 1915. In 1910 a 450-mt. length dock was opened in Puerto Madryn. The railway station would be opened three years after.
