Our company has been successfully producing various railway track components for many years. Currently, our portfolio includes mainly SZN self-adjusting facing point locks for turnouts. Their type code is SZS.

Since they are relatively specialized products, some basic information can be found below that makes it easier to use the nomenclature in this branch.

Railway turnouts are positions where tracks are split to allow trains to change tracks. Depending on the environmental conditions and the standard of the track on a given line, different turnouts are used. They are differentiated by a few characteristics, which are reflected in turnout coding.

Turnout type:

  • standard turnout (Rz) – right or left hand
  • 1-sided interlaced turnout (Rpj) – right or left hand
  • 2-sided interlaced turnout (Rpd)
  • symmetric turnout (Rps)
  • unsymmetric curved turnout (Rłj) – right or left hand
  • unsymmetric Y-turnout (Rłd)
  • single slip (Rkp)
  • double slip (Rkpd

Type of rail used in a turnout:

  • S42
  • 49E1 (equivalent of S49)
  • 60E1 (equivalent of S60 or UIC60 )

Diverging track curve radius expressed in meters:

140; 150; 190; 205; 300; 500; 760; 1200; 2500

Turnout angle express with a ratio:

1:4,8; 1:5; 1:6,6; 1:7; 1:7,5; 1:9; 1:10; 1:12; 1:14; 1:18,5; 1:26,5

There are also many other design features in turnout descriptions, however, these are the main parameters specified at the beginning of turnout codes. The most typical turnouts used in Polish railway tracks are as follows:

  • Rz 60E1-190-1:9 interchangeable with Rz UIC60-190-1:9
  • Rkpd 60E1-190-1:9 interchangeable with Rkpd UIC60-190-1:9
  • Rz 49E1-190-1:9 interchangeable with Rz S49-190-1:9
  • Rkpd 49E1-190-1:9 interchangeable with Rkpd S49-190-1:9

Each turnout includes three main elements: switch, frog and rails connecting the switch with the frog, while the switch is the main actuating device to move the train from one track to another. The switch is controlled with the locking device including the switch motor and the point lock.

Basically there are two types of locks: hook type and slide type. In Poland, the most popular are the slide-type point locks. They are included in our portfolio.

The following components are included in a typical slide-type point lock:

  • lock support (usually it is support OZA4, support OZB12, support OZA3, support OZB13)
  • lock clamp (usually it is clamp KRA5, clamp KRB3A, clamp KRA1, clamp KRA2)
  • rod
  • slide assembly

Additionally, the lock includes some minor elements: eccentric adjusting pin, locking pin, slide bush, connector, frame, centric sleeves, spacers and cotter pins.

All these components are available in our current portfolio.
