A rail support block assembly includes a resilient member and a molded block having a top, a bottom and peripheral wall. The block is adapted for fastening one or more rails on the top. The prefabricated resilient member has an outer tray and inner tray arranged within the outer tray, and includes a resilient intermediate structure between the trays. The block is molded in a block mold into with the moldable material is introduced and allowed to harden. The block is fixed in the inner tray to extend under the bottom of the block and along a lower region of the peripheral wall. The resilient member may form a part of the block mold, so that a mold member combined with the resilient member delimit the mold for the block. The moldable material is introduced and adheres directly to the inner tray of the prefabricated resilient member.

1. A resilient rail support block assembly adapted to be embedded in or mounted on a railway substructure, said block assembly comprising: a moulded block having a top, a bottom and peripheral wall, said moulded block being formed of a hardened mouldable material and being adapted for fastening one or more rails on the top of said block; a prefabricated resilient member having an outer tray, an inner tray arranged within said outer tray, and a resilient intermediate structure comprising a layer of elastomeric material disposed between said outer and inner trays, wherein at least said inner tray includes at least one sheet of a 3-dimensional open structure having interstices, and wherein the moulded block is fixed in the inner tray such that the inner tray extends over the bottom of the moulded block and along at least a lower region of the peripheral wall of the moulded block and the hardened mouldable material is entered into said interstices of at least the inner tray. 2. A resilient rail support block assembly according to claim 1, wherein the outer tray is comprised of a sheet material of a 3-dimensional open structure having interstices. 3. A resilient rail support block assembly according to claim 1, wherein the outer tray includes inward sloping peripheral walls. 4. A resilient rail support block assembly according to claim 1, wherein moulded block has a lower portion around which the inner tray extends and an upper portion upwardly protruding from the inner tray. 5. A resilient rail support block assembly according to claim 1, wherein the hardened mouldable material is concrete. 6. A resilient rail support block assembly according to claim 1, wherein the top of the block is provided with one or more rail fastener members that are directly integrated in the block and fixed to the block by the hardened mouldable material. 7. A resilient rail support block assembly according to claim 1, wherein said layer of elastomeric material is a plate of elastic foam material. 8. A resilient rail support block assembly adapted to be embedded in or mounted on a railway substructure, said block assembly comprising: a moulded block having a top, a bottom and peripheral wall, said moulded block being formed of a hardened mouldable material and being adapted for fastening one or more rails on the top of said block; a prefabricated resilient member having an outer tray, an inner tray arranged within said outer tray, and a resilient intermediate structure disposed between said outer and inner trays, wherein the moulded block has a lower portion and wherein the inner tray extends over the bottom of the moulded block and along a lower region of the moulded block, wherein the moulded block has an upper portion upwardly protruding from the inner tray, wherein the inner tray on an inner face thereof directed to the moulded block has adhesion enhancing formations to which the hardened mouldable material of the block is adhered directly. 9. A resilient rail support block assembly according to claim 8, wherein said adhesion enhancing formations on an inner face of the inner tray comprise one or more of ribs, lugs, loops, mush-room shaped projections, and hooks. 10. A resilient rail support block assembly according to claim 8, wherein said adhesion enhancing formations on an inner face of the inner tray comprise a rough mineral coating. 11. A resilient rail support block assembly according to claim 8, wherein said adhesion enhancing formations on an inner face of the inner tray are comprised of at least one sheet of a 3-dimensional open structure having interstices, wherein the hardened mouldable material is entered into said interstices. 12. A resilient rail support block assembly according to claim 8, wherein the hardened mouldable material is concrete. 13. A resilient rail support block assembly according to claim 8, wherein the resilient intermediate structure comprises a layer of elastomeric material. 14. A resilient rail support block assembly according to claim 13, wherein said layer of elastomeric material is a plate of elastic foam material.
