Together with lines R1, R2 and R3, the R4 (then simply numbered line 4) started services in 1989 as one of the first lines of the Cercanías commuter rail system for Barcelona, known as Rodalies Barcelona.[3] In 1995, the branch line to Cerdanyola Universitat railway station opened for passenger service and was incorporated as part of line R4.[4] With the creation of Barcelona commuter rail service line R7 in 2005, the branch line was transferred to the R7.[5] In the long-term future, it is projected that the route of the R4 south of Barcelona will be transferred to the R2, and all its services will terminate at Barcelona–El Prat Airport.[6]
