QUALITY AND ENVIRONMENTAL MANAGEMENT IN THE RAILWAY INDUSTRY

 

Safety, traceability, and sustainability—on the same track.

In the railway industry, every component is a critical link in the chain, from track safety to operational efficiency.

INOTIM approaches quality and environmental management not merely as a requirement, but as an engineering discipline based on traceability, measurable performance, and continuous improvement.

INOTIM Approach: Integrated Management System

  • Quality: Process standardization in line with ISO 9001 & IRIS/ISO 22163

  • Environment: Waste, water, and energy management in accordance with ISO 14001

  • Occupational Health & Safety: Risk-based control in line with ISO 45001

  • ECM Compliance: Maintenance management integration within the framework of (EU) 2019/779

  • Traceability: End-to-end records from material lot to field feedback

End-to-End Traceability

Material → Production → Cleaning → Assembly → Testing → Shipment → Field

  • Lot/serial numbers and 3.1 certificates (EN 10204)

  • Process parameters such as temperature, time, pressure, and ultrasonic power

  • Inspection & test reports (NDT, dimensional measurement)

  • Digital documentation (DMS), revision control, and approval matrix

Note: In ultrasonic and tunnel-type washing processes, the “cleaning recipe” (time–temperature–power–chemical) is automatically logged.

Environmental Management and Resource Efficiency

  • Water Management: Multi-stage filtration, recovery, and conductivity monitoring

  • Energy Management: Heat recovery, ECO mode, and VFD-controlled motors

  • Chemical Management: Dosing/pH control, MSDS management, and bath-life monitoring

  • Waste Management: Classification, temporary storage, and disposal records in line with ISO 14001

Process Assurance and Validation

  • Process FMEA & Control Plan: Measurable targets for Critical-to-Quality (CTQ) characteristics

  • Validation Tests: Cleaning validation, pressure/leak testing, and functional tests

  • Calibration: Planned calibration of measuring devices and sensors (≥ every 6 months)

  • Internal Audits: Regular audit cycles focused on ISO/IRIS and ECM requirements

Performance Indicators (KPIs)

  • FPY / First Pass Yield

  • Downtime & Failure Rate (MTBF/MTTR)

  • kWh/Part, Liters of Water/Part

  • Root Cause / 8D Closure Time

  • Supplier Quality Index (SQI)

Field Support and Continuous Improvement

  • CAPA (Corrective and Preventive Action) – root-cause analysis and effectiveness tracking

  • Gemba & 5S – visual management at workshop level

  • Training Programs – modular training for operators, maintenance, and quality teams

  • Digital Dashboards – real-time quality & environmental performance indicators

Quick Audit-Readiness Checklist

  • Current Quality/Environmental Policy published

  • Control Plan & FMEA available for all processes

  • Traceability Report (lot → product → field) available instantly

  • Chemical, waste, and energy records are up to date

  • Calibration and training records are complete

  • Maintenance documentation completed according to ECM requirements

FAQ

What is the difference between IRIS and ISO 9001?
IRIS/ISO 22163 is a railway-specific quality model focused on the supply chain, RAMS, and product lifecycle management.

How is ECM integration carried out?
Maintenance plans, traceability records, and conformity reports are digitally matched with ECM modules.

How do we measure environmental performance?
Indicators such as kWh/Part, Liters/Part, chemical consumption, and waste recovery rates are reported monthly.
