Indian Railways launched an AI-based stain detection pilot on 24 July 2026 at mechanised laundries in Pune Division (Central Railway) and Jaipur and Jodhpur divisions (North Western Railway).
Pilot and Locations
- Launch date: 24 July 2026.
- Divisions involved: Pune (Central Railway); Jaipur and Jodhpur (North Western Railway).
- Setting: Mechanised laundries that process linen for passenger services.
Technology and Function
- Components: Automated cameras, computer vision modules and machine learning inference engines.
- Operation: Images of washed linen are analysed to classify items as ‘acceptable’ or ‘stained’.
- Data requirement: Supervised models trained on labelled images of stains and clean linen.
- Integration: Designed to work alongside existing whiteness measurement (Whito‑Meter) and CCTV monitoring.
Linen Types and Service Protocols
- AC bedroll packet: Typically contains two bed sheets, one pillow cover and one hand towel.
- Blanket covers: Provided to AC passengers on North Western Railway; single‑use wash practice noted on Vande Bharat Sleeper (Kamakhya–Howrah).
- Quality checkpoints: Visual inspection, whiteness scoring and AI detection form layered checks.
IASPOINT Booster Facts
- Computer vision: AI subfield that enables machines to interpret images and video for tasks such as detection and classification.
- Machine learning: Algorithms that improve pattern recognition from data; includes supervised learning for image labels.
- Whito‑Meter: Instrument to quantify linen whiteness for quality control in laundries.
- Railway zones: Indian Railways is organised into zones; North Western and Central are two such zones.
