Claim:
A method for manufacturing a resilient rail support block assembly, which assembly is adapted to be embedded in or mounted on a railway substructure and which assembly comprises a prefabricated resilient member and a moulded block having a top, a bottom and peripheral wall, said block being adapted for fastening one or more rails on the top of said block, wherein the prefabricated resilient member has an outer tray and inner tray arranged within said outer tray, and wherein said prefabricated resilient member comprises a resilient intermediate structure arranged between said outer and inner trays, and wherein the block is moulded, in a block mould, with a mouldable material, which is introduced and allowed to harden, and wherein the block is fixed in the inner tray so as to extend under the bottom of the block and along at least a lower region of the peripheral wall of the block, wherein the prefabricated resilient member is used to form a part of the block mould, so that one or more additional block mould members combined with said prefabricated resilient member delimit a mould cavity for the block, the mouldable material being introduced into said mould cavity and thereby adhering directly to the inner tray of the prefabricated resilient member.
