From Bilthoven Station to the PBL(located at RIVM)
The PBL is about a 25-minute walk from Bilthoven train station. You can also hire a bicycle near the station. A taxi from the station will bring you to the same place.
The RIVM also operates a shuttle service to and from the station for its employees (and visitors). This service operates between approximately 7.30 and 9.25 in the mornings and between 3.30 and 5.25 in the afternoons. You can identify the minibuses by their RIVM logos. Buses wait around the corner from the station in the first street on your right (assuming you turned right when leaving the station). Buses leave the RIVM in front of the reception office.
