We are planning to stay at a hotel near Catalunya Metro/train station. I looked on the TMB map and saw that there are two lines that pass from Catalunya to Cornellà Centre (R1 and R4). Are these trains? I couldn't find their time tables on the TMB site. How much time does that ride take? Is it more than 30 minutes? And how frequently do these trains run?
Another question, how long is the ride from Diagonal metro station using L5 to Cornellà Centre?
I really appreciate your help.
