Travelling by train

Last summer we went to Barcelona to visit to a friend of my family.
First, the friend of my mother us invited to lunch to a restaurant which was in the center of the city.
We caught a train in Santa Coloma in the station. After that we got on the train and I was playing with the child of the my mother's friend. During the trip we made three stops in the stations.
Finally, we arrived at the restaurant and then returned home.
It was a great trip!
