UNILOCK Control System

UNILOCK is a control system for freight, urban and mixed traffic.

The application of the UNILOCK systems is in local transport and long distance transport. The system can be realized with a safety integrity level up to SIL3 depending on the requirements. The control Cabinet modules provide universal mounting possibilities, e.g. on concrete and metal foundation or as direct cable duct mounting.


  • High availability
  • Flexible installation in all signal designs and point designs
  • Reduced maintenance effort
  • Fast and easy installation
  • Low life cycle costs
  • Modern technology with enhanced diagnosis possibilities
  • Well-tested design with an excellent record of success in all climatic conditions.
  • Modular design, subsequent enhancements of the system can be made with little effort
  • Customized solutions even for difficult use cases
  • Supply voltage from 24 V until 750 V AC and DC (also from renewable energies)
  • Easy mounting of the modules and simple connection of the cables and wires to the module

UNILOCK - One product, many variants


The UNILOCK DEPOT system focuses on a holistic solution that independently regulates all vehicle traffic within the depot boundaries

  • Different concepts for switch the point and making shunting routes can be implemented here.
  • Shunting routes can be requested with the vehicle communicsation, the dispatcher and the manual control elements

By separating the system into different ranges is a clear selection and different operation rights are possible Moreover, the use and involvement of superior or existing sub systems are possible.


UNILOCK TCS/EWS – Turnout Control System

Turnout Control Systems are self-contained turnout controls that are independent from superior systems (visualisations). Furthermore, additional systems like point heating systems, vehicle communication, track circuits etc. are evaluated and controlled by the system.

  • Switch commands can be given locally with a control panel in the signal
  • The systems can control and monitor a small to medium range up to 4 points


UNILOCK EOW – Locally electric operated Turnout

  • In shunting areas with low velocity the EOW enable the central or decentral control and monitoring of one or more points
  • The operation is done either by means of push buttons or display boards in the track
  • EOW usually have no superior controls


UNILOCK ATP/TUZ – Automatic Train Protection

In principle, ATP systems are used to monitor train movements on single-track sections with train control operation. They support the dispatcher and can avoid accidents by actively switching on train stop.

  • For safe train detection axle counters are used and track magnets are used for train protection
  • Besides the central operation place (depending on which form of train protection is used) the modules/train stations are connected amongst each other
  • Shunting works in a train station are also considered by the system


UNILOCK SCS/FSA – Signaling Control System

  • UNILOCK SCS are used for local transport
  • They control the drive commands for the individual trams with driving signals
  • With track formation and monitoring, they avoid collisions or dangerous driving situations


UNILOCK BÜ/LC – Level Crossing

  • At the UNILOCK Level Crossing (LC) the traffic route for motor vehicles of all kinds is blocked for the period of the train crossing
  • Pedestrian or cyclist crossings can be integrated here
  • Train rides are e.g. detected via axle counters and the control program of the barriers and signals are triggered
  • The control can be done independently via superior control systems


UNILOCK FWA – Pedestrian Warning

The pedestrian warning system allows the safe crossing of rail bound routes.

  • Similar to the UNILOCK LC system, special guidelines apply here
  • Through the use of flasher lamps and acoustic signals, people are warned visually and acoustically by an approaching vehicle
  • The signals are respectively switched with track switching devices
  • Mostly with track circuits or axle counter
