Has anybody got experience with taking the TerraSur to Chillan and renting a car for a little tourismo? My wife and I would like to take the train Sur for a long weekend around the first of April. We aren't familiar with the train service so I was hoping to get some feedback. right now, the tentative plan is to head to Chillan and visit the Termas de Chillan. How is the train ride? Is it somewhat reliable? Comfortable? Any feedback would be appreciatted.
