FIELD: railway transport; permanent ways; adjustment of track gauge in tack curved sections at increase in track gauge to maximum tolerable values caused by side wear of rail head. SUBSTANCE: proposed rail fastenings can be used both on wooden and reinforced concrete sleepers. Rail fastening has baseplate 1 with two flanges 5 and flat 6 located between flanges 5 for mounting foot of rail 7. Baseplate 1 is connected to sleeper 2 by fastenings 3 fitted in holes 4. Adjusting member 8, L-shaped in cross section, is installed at one side of rail 7 with possibility of re-fitting to other side and pressing by means of clamp 9. Distance between flanges 5 exceeds width of foot of rail 7 by value "a" of thickness of adjusting L-shaped member 8. EFFECT: enlarged operating capabilities. 2 dwg
