The derailer is intended for securing tracks against uncontrolled entry of rolling stock from the side track.

Depending on the type of rails to which they are to be mounted, we make derailers:

• Wk / S49 designed for installation in tracks with S42 and S 49 rails
• Wk / S60 - designed for mounting on tracks with S60 rails

Our derailers are designed as:

• manually controlled via a signal lamp turning device with counterweight,
• mechanically controlled with all types of derailer drives,
• electrically controlled with any type of points drive,
• equipped with two locks that enable closing in the position applied to or removed from the track.
