Where can I start the journey? Does it need to be a rail station or can I also use the bus?

You can start your journey from a bus stop near your home address provided that this is not further north than the border with the municipality of Sittard-Geleen. You can also get on a train at any station on the service between Roermond and Maastricht Randwyck (Arriva / NS) and the service between Kerkrade Centrum and Maastricht Randwyck (Arriva).
Occasionally it may be faster to cycle or travel by car to a train station or bus stop instead of using public transport for any initial part of the journey.
For further information see the Maastricht Bereikbaar travel planner at www.maastrichtbereikbaar.nl and indicate your preference on the ‘OV-advies’ page under the heading 'By bicycle or by car to the station’.
