This turnout features the advanced design compared to serial turnouts М1740 , У1740, Dn 290, КС 6511-01, КС 6511-02, КС 6511-03, 2768.

Design features:

  1. Pads with high flanges.
  2. Elastic fastening in the stock rail assembly with a point and guard rail assembly with a flat plate.
  3. КБЛ-65 cast pads in the switching zone are provided with the cast ПКЛ clip.
  4. Adjustable second coupling rod.
  5. Connecting strips in the switch zone.
  6. Monoblock frog with shockless tread surface with welded rail ends on pads with high flanges.
  7. Spring points of tangent type with welded rail ends on special heel plates.
  8. Rigid heel fastening of the points.
  9. Switch on plates with welded pads without rail supports.
  10. Points are hardened using induction hardening method, cut pieces and stock rails made of surface-hardened rails.
  11. Anchorage between points and stock rails.
  12. Independent guard rail made of guard rail angle section СП850 with the possibility of adjusting the chute.
  13. Insulated joint with polymer composite overlays.
  14. Turnout switch is laid on the reinforced concrete beams from pr.1740 and corresponds to it by the geometry (except the tail of the frog).

Design features of the turnout switch:

– designed for welding into continuous welded rail track (spring points of tangent type with welded rail ends, frog rail ends);

– installation of elastic clips instead of ПКЛ is suggested;

– designed for 160 km/h speed on the straight track and 50 km/h on the side track.
