Abetong concrete railway sleepers are manufactured according to a special system known as the Abetong Long Line Method. It is characterized by casting beds of 100-180 meters in length in which 30-70 quadruple sleeper moulds are placed one after the other. The sleepers are cast upside down and left to cure in the moulds during the night.

Among these sleepers, while the twin-blocks (in Fig. 1 a–b) are produced with ordinary reinforced concrete (RCS-type sleeper), almost all of the mono-block types (in Fig. 1 c–d) are preferred to be produced with prestressed concrete (PCS-type sleeper) [2].As frequently mentioned in the literature and seen in the statistics of railway companies, …
