Additional lines on the Pacific coast were built in the subsequent decades . In 1940 , the National Railroads consisted of the following lines : Total : 382.48 km In the 1960s and 1970s , the railroad went into a decline , exacerbated further by the Managua earthquake of 1972 . The government reacted to this by constructing a 25.4 km branch from Ceiba Mocha to Puerto Somoza ( now Puerto Sandino ) in 1976 . This significantly increased productive operations and revenues , but did not reverse the long-term trend . Governmental subsidies were steadily increasing and passenger transport declining . The oldest line Corinto - León was abandoned in 1982 when floods damaged tracks . In 1993 , there were still 373 km of narrow gauge tracks in the Pacific region and isolated 3 km of standard gauge line at Puerto Cabezas in the Caribbean . Several trains a day carried passengers south from Managua to Granada , or north from the capital to León
