I did not say to avoiud ALL trains. I said not to take the train to Escobar. I did it recently with two Argentine friends and we were quite nervous. The station in Escobar is in a bad neighborhod. The passengers are very poor and if you look more prosperous you will really stand out. There is crime on bad train lines like this, believe me. It´s not the same as the line to Tigre which is safe. Some of the readers here are unbelievably sarcastic. Any word of advice, meant to help expats avoid trouble, is met with hostility if it does not praise Argentine to the skies. As I said, TEMAIKEN is superb in every way. Take the bus.
