History
The RER Jura network began operation on 14 December 2025.[1] Between Delémont and Porrentruy, the new R1 and R2 combine for half-hourly service, with hourly service to Delle (France) and Bonfol. This replaced a mix of Basel S-Bahn (S3), RegioExpress (RE56) and Regio (R51) services. The R11 and R22 provide hourly service from Porrentruy to Delle and Bonfol, respectively.[2] Services operate over the Delémont–Delle railway line of Swiss Federal Railways (SBB CFF FFS) and the Porrentruy–Bonfol railway line of Chemins de fer du Jura (CJ).
