This production process involves the placement of concrete into forms, compaction of the concrete, and its removal from the forms after a short period. Templates are installed into the concrete to indicate the position of the pre-stressing tendons. The templates are pulled out of the concrete after the forms are removed. After the concrete has reached sufficient strength, pre-stressing-steel needles are inserted into the sleeper, and the needles are pre-stressed with respect to the concrete by means of end anchors. This process requires only a small number of forms, since -  in the continuous production process, until pre-tensioning - only the sleepers removed from the forms need to be placed as required into intermediate storage.

Automated processes developed by RAIL.ONE for use in the fresh-concrete area  and likewise in the pre-stressing line - mean that this mode of production is cost-effective even if numerous different sleeper models (or non-prestressed-reinforcement bi-block sleepers) are being produced. This plant can also manufacture other products: e.g., noise absorbers made of drain concrete.
