The morning FES mixto heads east to San Salvador from Sitio del Nino across a black lava bed. The 14 is an FES original as indicated by the link on the front pilot instead of a knuckle coupler. The used equipment that FES acquired from the Oahu Railway and the IRCA had knuckle couplers, but for the most part the FES was a link and pin railroad up until it was absorbed into FENADESAL, the nationalized successor to the much more modern IRCA. All the knuckles were forked, so that they could be used interchangeably with the link and pin equipment. January 1968.
