Within the scope of the LHC injector upgrade it has been proposed to replace the present injector chain by new accelerators, LINAC4, SPL and PS2, for which new transfer lines will be required. In this report the beam line properties and requirements are summarized. Then the initial optics of these beam lines and their geometry are discussed. Particular attention is given to the injection and extraction regions where several beam lines have to intersect, imposing challenging constraints on the layout. Directions for optimisation are suggested
