sergio said:The fact that it terminates in Maipu without even a cross-platform connection prevents it from being integrated into the rail system. The pity is that the train does not begin at Retiro. Properly from Retiro run it could be a great plus for tourism - unfortunately these projects seldom ever get off the ground in Argentina.
Not physically possible to connect the two lines, and doesn't really make that much sense. The FFCC Mitre is Argentine Broad Gauge (~1.67 m) while the Tren de la Costa was remodeled in International Standard Gauge (~1.435 m).
The Tren de la Costa mirrors pretty much the Tigre line, and never had the kind of ridership of that one, which is why they decided to turn it into a tourist train (also due to its scenic route).
As far as a tren to NorDelta goes, I heard that they (TBA) were thinking about using the Diesel Hauled Double Decker prototype they had made to run a direct route, because seriously, I doubt people who choose to live in Nordelta would ride a train with "commoners". I doubt that anything will ever come of it though.
