Event Recorders

Functions of Event Recorders

EKE-Trainnet Event Recorder (ER) is an onboard data recorder for collecting and storing vital train-borne information.

The Event Recorder can record all kinds of data including audio and video streams.

Key features

EKE-Trainnet Event Recorders are able to record virtually any avail­able signals, analogue or digital. The Event Recorder can be pro­grammed to record safety critical information like train speed, train position or brake temperature. The Event Recorder can also record video streams from onboard digital video recorders (DVR) or directly from the cameras. For easy data retrieval, the stream format can be made compatible with your CCTV Software or any other video analy­sis Software that you are using. Alternatively, we can develop cus­tomized video analysis tools to fit your needs.

EKE-Trainnet Event Recorders have an Ethernet port and an RS-485 port at the front for easy access. The Ethernet port can be used to download the data stored in the recorder. Alternatively, the Ether­net port can be used to connect to a sub-system or an Ethernet Switch. The RS-485 port can also be connecting sub-systems.

All the EKE-Trainnet Event Record­ers are protected against shocks, vibration, humidity, temperature variations, excessive emissions and excessive voltages (following the EN50155 standard). The Event Recorder can be equipped with a rugged RMM module if crashworthiness according to IEEE 1482-1 and GM/RT2472-1 is required.

Front-panel imprints are available upon request.


Additional interfaces can be easily added to the EKE-Trainnet Event Recorder, as the system is modular. You can add bus interfaces such as MVB, CAN, S/L or Ethernet to connect with train sub-systems or Train Communication Network (TCN) in order to acquire data. You can also add Input/Output Interfaces to record various signals. Available I/O Interface Modules include Analogue Input, High Speed Analogue Input, Digital Input/Output, Digital Relay Output, Analogue Output and Pt-100/Pt-1000/NTC temperature sensor input.

For a compact and efficient sys­tem, EKE-Trainnet Event Recorder can be integrated as a part of a broader EKE-Train­net system, for instance, integrat­ed to a Gateway, a VCU or a TCMS.

Data retrieval and analysis

Data can be retrieved at any time via the Event Recorder Ethernet port using the EKE-Trainnet TIP Software (Train Inspection Program). The TIP Software enables the download and analysis of the train data. Alternatively, the data can be transferred to a USB stick, for convenient transport or storage. The data is easily imported from the USB stick to the TIP Software.

The EKE-Trainnet Event Recorder proves useful beyond traditional use following an incident. The retrieved data can be visualized with the TIP Software in order to perform regu­lar system performance analysis and train operational optimization.

Rugged Memory Module

EKE-Trainnet Rugged Memory Module (RMM) is available as an option whenever a high level of data protection is needed. This crash-proof construction guaran­tees that the memory board is protected against fire, magnetic fields and any liquids, as well as against any mechanical stress during an impact or continued pressure. In practice, the memory board is embedded in a protected fire insulation block, surrounded by a special steel case that is her­metically sealed.

The design of the EKE-Trainnet Rugged Memory Module fulfils the British (GM/RT2472-1.2002) and Euro­pean (EEIG 97E461-3.1998) crash­worthiness as well as the IEEE (1482.-1.1999) standards. This makes the EKE-Trainnet Event Record­er suitable for trains worldwide.

Juridical Recording Unit

EKE-Trainnet Juridical Recording Unit (JRU) is a train event recorder complying with the ERTMS/ETCS standard. The EKE-Trainnet JRU has all the features of the EKE-Trainnet Event Recorder and it is equipped with the EKE-Trainnet Rugged Memo­ry Module for data protection.

EKE-Trainnet JRU can record data from the ETCS (i.e. European Vi­tal Computer, EVC) and/or from nation-specific control systems (i.e. Specific Transmission Module, STM). The ETCS architecture illus­tration highlights the two stand­ard setup options.


As an option, a GNSS (Global Navigation Satellite System) re­ceiver can be integrated into the Event Recorder. Versions with GPS+GLONASS and GPS+BeiDou are available. This option requires 4TE of additional space in the rack (one free bus interface slot).

Racks and sizes

The modularity of the EKE- Trainnet Event Recorders means you can choose a rack size based on your needs: the more additional inter­faces or features you need, the larger is the rack that you need to select. Compact side mounted racks, 20TE, 44TE and 84TE standard rack mounted options are available.


Redundancy can be achieved by using 2 sets of modules or 2 separated event recorders. It is possible to create 2 independent event recorders in the same rack. Dual homing for Event Recorders using RMM is possible with an additional CPS-module. Dual homing can also be built up efficiently using CPD-module when crashworthiness (RMM) is not required.
