FIELD: construction.
SUBSTANCE: invention relates to the upper structure of a railway track. Reinforced concrete sleepers for a curved path section include a pair of under-rail platforms. Rail seat are performed with a change in track width from the standard value of 1,520 mm and with the change of the canting from the standard value of 1/20. On the one rail seat the canting is changed in the direction of increase, and on the other – in the direction of decrease. Step of the canting changing is from 1/100 to 1/60. Step of increasing the track width: 2–3 mm.
EFFECT: increase in the resource of the wheel-rail system is achieved.
