Method for manufacturing a resilient rail support block assembly

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.
