Subject: Re: RER (Réseau Express régional)
Hi, Grazeilla

I was buying this ticket at the window. By the way, it's very easy to use these trains between some metro stations inside the city. Instead of using the usual metro train, you can use RER which will save you time, because RER doesn't stop at each station in comparison to ordinary metro train. RER is a very good means of transport inside the city as well as in suburbs.
