Assuring Reliability and Safety in Rail Operations

The railway and metro sectors are defined by high demands for safety, reliability, and long-term asset integrity. Components, tracks, bridges, and rolling stock are subjected to immense mechanical stress and fatigue loading over decades of service. Ensuring their continued structural soundness is critical for preventing derailments, minimizing downtime, and protecting passenger safety.

BQCIS provides comprehensive independent inspection and testing services tailored to rail standards (EN, AREMA, FRA). Our expertise covers both the fixed infrastructure and the rolling stock assets. We utilize specialized Non-Destructive Testing (NDT) techniques to detect rail flaws, axle cracks, and weld defects in bogies and car bodies.

Our services include surveillance during the manufacturing of new rolling stock, periodic in-service inspection of tracks and bridges, and verification of maintenance and repair (M&R) quality. By providing certified inspection and verification, we help rail operators meet rigorous regulatory requirements and maximize the safe lifespan of their infrastructure.

Key Integrity Activities

Track and Infrastructure NDT Inspection

We conduct specialized non-destructive testing (NDT) for fixed infrastructure such as tracks, welded joints, and bridges. Using ultrasonic, magnetic particle, and guided-wave techniques, we locate internal flaws and fatigue cracks to prevent derailments and ensure long-term structural safety.

Rolling Stock Verification & Component Testing

Inspection of bogies, axles, and undercarriage structures through advanced NDT and welding quality checks. We verify new builds and overhauls against EN 15085 requirements, ensuring mechanical integrity and compliance before vehicles return to service.

Success Story

Axle Inspection Prevents Rolling Stock Derailment Risk

The Challenge:

A regional metro system initiated a fleet-wide axle inspection after a derailment incident was suspected to stem from fatigue damage in wheelsets.

Our Solution:

BQCIS deployed mobile NDT units using ultrasonic and magnetic particle testing (UT/MT) per EN 13260, ensuring in-situ coverage without service disruption.

The Result:

Several high-stress axles exhibiting sub-surface cracks were replaced proactively, preventing failure, extending fleet life, and safeguarding passengers and operations.
