Abstract	This document gives guidance for the design and tuning of secondary beam lines at CERN. Important aspects include principles and practical recipes for the design of secondary beam line optics, collimation as well as on secondary and tertiary particle production and the selection of specific particle types. The description of these aspects is kept rather general, although the examples are derived from CERN beam lines in the North Experimental Area at the CERN SPS and the East Area at the PS, as well as sometimes from the by now dismantled West Area. Considerations and constraints concerning choice and integration of equipment are explained with direct reference to the existing equipment and methods at CERN. The same applies to beam control and interlocks. After design and installation follows the commissioning and beam tuning. Practical guidance is given on how to proceed efficiently and effectively, again with the CERN beam lines, equipment and control system in mind. The document concludes with a few atypical and complex examples of beam lines that are or have been operated in the CERN North Area.
