UNISTAR CSV 24 Point Machine

Electro-hydraulic point machine with internal locking for freight and mixed traffic.

In the last decade the SIL4 certified UNISTAR CSV 24 has proven its extraordinary qualities in more than 40 countries in excess of 3.000 applications. Customers appreciate in particular:

  • Its stainless steel housing
  • The permanent and durable water tightness due to the special sealing system
  • Its Monoblock Hydraulic System with integrated operating cylinder
  • The clearly visible prism lock made of high- grade special steel
  • As well as its fully modular structure, significantly easing and reducing maintenance to the minimum

The point machine’s ultra-low profile enables for retrofit into existing earth boxes, thus avoiding any earth works!

Due to its continuously adjustable point opening UNISTAR CSV 24 is applicable for grooved rail as well as flat bottom rail turnouts with a throw range of 38 – 120 mm. Various fastening methods are available, like sleeper fixation angles, stock rail fixation, and earth boxes. All such fastening elements are made of hot dip galvanized steel, providing a long lasting corrosion protection.

With the UNISTAR CSV 24 a setting system is available which can be flexibly adapted to the respective requirements and conditions thanks to its fully modular structure.. The MTTR value of the point machine is only 15 minutes.


The compact version of the point machine has been specially developed for replacing existing point machines in earth boxes of the EH-71 and VS-60 series. While the UNISTAR CSV 24 has identical components, the construction of the UNISTAR CSV 24 COMPACT could be shortened by 156 mm due to a turned hydraulic unit.
