The lateral resistance to wheel loads of a 1,065 guage railway track consisting of 48 kg/m SATS rails, Pandrol lastenings and Type P-2 prestressed concrete sleepers on standard SATS ballast was determined in the laboratory. The axle load, degree of ballast compaction and rail temperature were the parameters which were varied. As concluded by earlier investigators the axle load and ballast compaction showed signilicant influences on the lateral resistance whereas the temperature effect was negligible. At standard tamped density the well-known Prud'homme formula conservatively predicted the lateral resistance per axle as H = 10 x axle load/3 kN.
