Data Acquisition and Recording | HaslerRail

In the event of an accident, data recording systems play a crucial role in determining the root cause. More recently, analyzing recorded data proactively has emerged as an effective means of preventing accidents. HaslerRail’s data recording system is suitable for both of these uses.

The HaslerRail TELOC® data recording system is built on a modular architecture that can be tailored to individual vehicles, projects, and environments, covering a full range of functions. Our engineers can configure the system to give you a high level of customization and freedom. In addition, because specific software is not required for each project, you can respond quickly when modifications or adjustments are needed.


Our modules include different types of Crash Protected Memory, as well as modules to enable a variety of input and output capabilities for wired signals and all types of bus interfaces (MVB, CAN, Profibus, Serial, etc.). We also offer the SABOB (Safety Board) card, with dedicated safety functions up to SIL2 and SIL4.

We can provide a range of peripheral devices, including a badge reader for gathering driver ID information and execution of specific functions based on the driver ID, and voice and video recorders. Finally, our gateway enables automated on-board to off-board data transfer through selectable communication channels.

All recorded data is analyzed using our proprietary EVA+ evaluation suite. The software is used to reconstruct events and evaluate predefined patterns.


The TELOC® event recorders are available with different enclosure designs to comply with form-fit requirements.

Visualisation Solutions and Speed Indicators | HaslerRail

A railway vehicle’s human-machine interface (HMI), or display solution, is the driver’s main point of interaction with the vehicle. Therefore, it is crucial to safe, reliable operation.

HaslerRail offers a wide range of display solutions and speed indicators to meet a variety of rail vehicle requirements.

Our digital speed indicator is both simple and robust. Speed is displayed on an illuminated ring meter or digitally. Our moving coil speed indicator is also simple and robust. This highly configurable device comes in circular or square casings and in a range of sizes. Larger casings can incorporate two independent coils and up to four different-colored lamps. Finally, a small speed or distance indicator can be added.

The SPEEDO is a robust device with additional features. A feedback encoder system supervises the pointer position. It also features an additional illuminated ring meter, four lamps, a flag, and a small LCD display.

HaslerRail’s acquisition of Pixy brought a new range of display solutions to our speed indicator line.

All of our speed sensors, display solutions, and software are built on the latest technology, are designed to be robust and reliable, and have long track records in service, including in harsh conditions. Whether you are a car builder or systems integrator, you can count on HaslerRail to bring you solutions you can count on.

Speed Sensing and Odometry | HaslerRail

Rail vehicles need robust and reliable speed measurement capabilities to ensure safe, reliable and seamless operation. HaslerRail can provide a complete portfolio of speed sensors and related products to meet a wide range of needs.


HaslerRail speed sensors have been found in all kinds of rail vehicles for more than a century. Today, we offer proven, reliable pulse generators, wave reflection sensors, and Hall effect sensors with long service histories.

Pulse generators convert the axle’s rotational motion into an electrical signal. These optical systems are designed to withstand extreme conditions, including high mechanical stress.

Our CORRail 1000 wave reflection sensor is a track-bed independent and non-slip/slide sensor that can take objective measurements. It directly measures a vehicle’s speed and operating direction using the railhead as a reference.


Our Hall effect sensor picks up a speed signal from a toothed target wheel (gear). It is ideal for situations where space is limited.


All of these sensors are available in a variety of versions to meet your needs. And, if you would like to merge signals from different sensors, HaslerRail’s event recording system includes speed evaluation capabilities that can perform this task.

Our Product Range

- Pulse Generators

- CORRail®1000

- Hall Effect Sensors

- Odometry Solutions


Energy Metering | HaslerRail

When it comes to energy efficiency, the rail industry needs standardized, interoperable energy metering, measurement, calculation, and data exchange tools. HaslerRail solutions help rolling stock builders, OEMs and integrators, and operators meet the new requirements in the EN 50463 standard.

The separation of rail infrastructure and operations has created new needs like cost allocation. In addition, rail industry stake holders must comply with EU regulations requiring them to collect train energy consumption data in real time and store it on a ground server, validate energy consumption and allocate energy costs, and install energy meters on all new and overhauled rolling stock operating on networks with Data Collection Systems (DCS).

HaslerRail offers a full range of solutions to meet these needs, from AC and DC meters to comprehensive energy management systems. Our Energy Portal ground server can pre-process energy data for billing, and REM102 is an all-in-one EN 50463-compliant energy meter that integrates multiple functions, including energy measurement and calculation, data storage and processing, GPS receiver, and radio communications.

Our Product Range

- AC and DC Meters

- Indoor Meters with Integrated DC Voltage and Current Sensors

- Energy Management Systems

- Outdoor Integrated AC and DC Voltage and Current Sensors

- Multifunction Indoor DC Voltage and Current Sensors


Control, Protection and I/O | HaslerRail

This generic concept is implemented by the Train Control and Management System (TCMS) as follows: the control and diagnostics, is managed by Vehicle Control Units (VCUs), while sensing is done by Remotes Input/Output devices (RIOs). Sensing and Control are connected via the communication infrastructure providing the safe and secure flow of information.

HaslerRail offers a complete range of control and protection products.

Our RaPLC TCMS platform includes VCUs and RIOs. The highly-standardized platform is built on a modular architecture for flexible configuration, scalability, and interfacing with subsystems. It is also very cost effective. The VCUs are programmable via the IEC61131-3 family of languages by the customer. The VCUs and RIOs can communicate via the most commonly-used protocols (Ethernet, MVB, CAN, etc.).


The RTP100 traction protection device, designed for integration into the TCMS, provides a cost-effective, very flexible and reliable solution for implementing electrical protection and catenary detection on board the vehicle.


We also offer an ETCS Cold Movement Detection (CMD) device. It delivers a SIL4 function to supervise vehicle movement during the power off phase, transmitting the information to the ETCS on-board system, saving time and lowering operating costs. Drivers no longer have to operate in downgraded mode until the next coordination location to synchronize their positions with the wayside ETCS beacon.


Finally, with the CMD it is possible to reliably determine if a vehicle has been moved during the power off phase of the ETCS on-board system.

Our Product Range

- Vehicle Control Units (VCU)

- Traction Protection Relay Solutions

- Cold Movement Detection SIL4

- Remote I/O Units
