Frequently Asked Questions
What is an Event Recorder?
An Event Recorder, often referred to as a “train black box” is an onboard data recorder for collecting and storing a wide array of operational data related to the train’s performance and activities. The primary purpose of the event recorder is to capture and store critical information that can be used for accident investigation, safety analysis, and operational reviews.
What is Train Data Recorder?
A train data recorder is a system that continuously records operational, diagnostic and safety-related information from onboard train systems. Data such as speed, braking activity, door status, driver actions and system events can be stored for fault analysis, maintenance and incident investigation. Train data recorders are also commonly referred to as event recorders.
What is a Train Black Box?
A train black box is an informal term for an Event Recorder or Train Data Recorder. Like the flight recorders used in aircraft, it captures and stores operational data from the train so that engineers can analyse system behaviour, investigate incidents, and review performance. Although the term “black box” is widely used, the official industry terms are Event Recorder, Train Data Recorder, or Juridical Recording Unit (JRU), depending on the application.
What is a Juridical Recording Unit (JRU)?
A Juridical Recording Unit (JRU) is a specialised type of train data recorder designed to meet specific regulatory and investigation requirements. It records defined operational data and stores it in protected memory so that information remains available for incident investigations and safety reviews. JRUs are commonly associated with ETCS-equipped trains and applications where regulations specify the data that must be recorded.
What is the Difference Between an Event Recorder and a Train Data Recorder?
There is generally no difference. The terms “event recorder” and “train data recorder” are often used interchangeably within the train industry. Both refer to a system that records onboard operational data to support diagnostics, maintenance, incident investigation and regulatory compliance.
What is the Difference Between a Rugged and Non-Rugged Event Recorder?
Both rugged and non-rugged Event Recorders capture and store train operational data. The main difference is how the recorded data is protected.
A non-rugged Event Recorder stores data in standard memory and is suitable for many operational and maintenance applications. A rugged Event Recorder includes a crash-protected memory module designed to protect recorded data from impact, fire, liquids, magnetic fields and other extreme conditions. This protection helps ensure that critical information remains available following a serious incident.
What Data Can a Train Data Recorder Capture?
A train data recorder can capture information from a wide range of onboard systems, including train speed, location, braking systems, traction equipment, door systems, driver controls, signalling interfaces and other analogue or digital inputs. The exact signals recorded can be configured to meet project requirements.
How Long is Data Stored in a Train Data Recorder?
Data retention depends on the configuration, memory capacity and amount of data being recorded. Train Data Recorders typically use cyclic storage, where the oldest information is automatically overwritten when storage limits are reached. Critical data can be protected through event-triggered locking, preventing it from being overwritten. EKE-Trainnet® Event Recorders support flexible memory configurations to match project requirements.
Why is a Train Data Recorder Important?
Train data recorders provide an accurate historical record of train operation. Recorded data can be used to investigate incidents, analyse faults, support preventative maintenance activities and demonstrate compliance with industry requirements.
Can an Event Recorder be Integrated with a TCMS?
Yes. EKE-Trainnet® Event Recorders are built on the same modular platform as the wider TCMS and can be integrated with onboard networks, I/O modules and other train systems. This enables the recorder to capture operational information from multiple subsystems while reducing integration effort and avoiding unnecessary duplication of hardware.
What is the Train Inspection Program or TIP Tool?
A Train Inspection Program (TIP) is a software tool used for the transfer and analysis of data recorded in the EKE-Trainnet® Event Recorder.

Do you support 24-110VDC?
We have a range of different power supplies supporting 24-11VDC:
- PSV1133: 24V

- PSV2513: 36..52V
- PSV3034: 48..110V
- PSV1018: 110V
