Described herein is a method which enables ties for the track superstructure which have optimized performance characteristics to be produced in an operationally reliable and cost-effective manner. To this effect， the method according to the invention provides the following steps: a) providing a mixture which consists of 10-60 wt.% of a granulate of a thermoformable polymer and， as the rest， a sand having a bulk density of 1.4-2.0 g/cm3， b) heating the mixture to a temperature of 150-180°C， c) filling the mixture into a press mould in the shape of the tie， d) pressing the mixture in the mould at a pressing pressure of 1-5 MPa measured in the mixture over a pressing duration of up to 60 min; e) removing the tie from the mould.
