Does Dṛṣṭi-Sārathi apply the brakes or take control?

No, and that is a deliberate design position. It is advisory: it alerts, it never overrides. A perception system that intervenes has to be certified to a completely different standard, and a system that quietly acts against the pilot's judgement erodes the trust it needs to be useful.

How does this relate to Kavach?

Kavach is a train protection system built around signalling and train separation. Dṛṣṭi-Sārathi looks at what is physically on the track ahead — obstructions, people, livestock — which is a different class of hazard that signalling-based protection does not address.

Does it work at night and in poor visibility?

Degraded visibility is the condition where a second pair of eyes is most valuable, so it is a design target rather than an edge case. Actual performance envelope depends on the sensor configuration chosen for the deployment.

What happens to the video it captures?

Processing is done on the locomotive rather than streamed off it. Retention and access follow the operator's policy, which matters because a forward-facing camera on a locomotive is subject to the same governance concerns as any other crew-facing recording.

Locomotive Vision & Perception

Dṛṣṭi-Sārathi
A second pair of eyes that never blinks.

An always-vigilant perception layer for the locomotive cab. It keeps watch on the track ahead and surfaces what matters — supporting the Loco Pilot's awareness without ever replacing their judgement.

The problem

Cab perception rests on a single point of attention

A Loco Pilot must read every signal, marker and potential hazard — across long shifts, in fog, glare, monsoon and night. Human attention is finite, and existing cab cameras only record after the fact. Dṛṣṭi-Sārathi adds a vigilant second pair of eyes, without removing the Pilot's authority.

The difference it makes

A vigilant second pair of eyes on the track ahead

Constant vigilance

The view ahead is watched continuously, without fatigue — a steady second pair of eyes across long shifts and difficult conditions.

Earlier awareness of risk

What matters ahead — and any developing hazard — is surfaced to the Pilot as advisory support, giving them earlier awareness when it counts.

Advisory by design

The system informs; it never acts on the locomotive. The Pilot stays firmly in command — better supported, never overridden.

Why it matters

Support for judgement, not a replacement for it

VigilantA second pair of eyes that never tires.

EarlierAwareness of risk, sooner.

A second pair of eyes — built for railway vigilance

Dṛṣṭi-Sārathi is ready for deployments that want to give the cab a vigilance support layer without overriding the Pilot's authority. Book a discovery call.
