General Roca Railroad's nameless train number 317 leaves the City of Buenos Aires passing through the southern suburbs at Banfield, 12 kilomtres from Plaza Constitución Terminal. General Electric export-model U18C #8101 heads the train, making a rare appearance in a passenger service assignment after the massive incorporation of General Motors' GT22 units in the early 1980's and the complementary pool of G12's demoted the almost thirty-year old G.E.'s to less demanding duties, mainly yard switching and freight services on secondary mainlines.
