Every Second, On the Record
Speed, commands, subsystem states, and fault events are logged continuously, so the sequence of any journey can be reconstructed after the fact.

Event Recorder: The Black Box of the Train
The Bacancy Systems event recorder logs what the train did and when: speed, driver commands, brake and traction states, door status, and fault events, held in protected storage for diagnostics and incident review. Engineered to EN 50155 and designed, populated, and tested in-house in Ahmedabad, it turns every journey into a record maintenance teams and investigators can rely on.

Why Bacancy Systems Recorder
When It Matters, the Record Is There
After an incident or a fault, the questions are always the same: what happened, when, and in what order. We built the recorder so the answers are already on board, structured, time-stamped, and retrievable.
01 02 Engineered to EN 50155
Built for the temperature, shock, vibration, and EMC of rail service, because a recorder that fails with the train records nothing at all.
03 From Incident to Insight
Structured, time-synchronized logs cut investigation and fault-finding from days of guesswork to hours of analysis.
04 Depot-Friendly Retrieval
Data downloads at the depot, and paired with Bacancy Systems Remote Monitoring, key events reach the maintenance desk before the train does.
05 Full Stack From One Vendor
The recorder joins the TCMS Unit, traction control, and remote monitoring, so logging is designed into the rail stack, not bolted on.
Where It Runs
A Record for Every Class of Service
From dense metro duty to long-haul mainline runs, the recorder captures the same dependable evidence, and refurbishment programs can add it to fleets that never had structured logging at all.
Incident review on mainline and metro fleets
Maintenance diagnostics and fault sequencing
Driver training and operations analysis
Refurbishment programs adding structured logging
Fleet health data feeding remote monitoring

FAQ
Event Recorder: Frequently Asked Questions
An event recorder is the on-board data logger of a train, often called the rail equivalent of a black box. It continuously records speed, driver commands, brake and traction states, door status, and fault events, so the sequence of any journey can be reconstructed for diagnostics or incident review.
The role is the same: preserve a trustworthy record of what the vehicle did. The rail version is engineered to rolling stock standards such as EN 50155 and records train-specific channels like traction, braking, and door states rather than flight parameters.
It logs speed, driver commands, brake and traction states, door status, and fault events with synchronized time stamps. The exact channel list is configurable per fleet and confirmed in the datasheet.
Yes. Data downloads at the depot, and when paired with Bacancy Systems Remote Monitoring, selected events and health data stream off the train while it is still in service.
Every board is designed, populated, and tested in-house at Bacancy Systems' facilities in Ahmedabad, India. It is a Make in India product backed by 16+ years of embedded engineering experience.
