Electrical Engineering & Diagnostic Services for Battery-Electric Rolling Stock

EnerGenix Engineering provides specialist electrical engineering, fault-finding, and diagnostic services for battery-electric locomotives and rolling stock, including legacy and obsolete traction systems. ‍

‍

Specialist Electrical Engineering for Battery-Electric Locomotives

We deliver professional electrical engineering services for battery-electric locomotives operating in heritage, industrial, and specialist railway environments. Our work supports asset owners where modern replacements are unavailable, impractical, or cost-prohibitive.

‍

Battery-Electric Rolling Stock Diagnostics & Fault-Finding

We carry out structured electrical diagnostics using specialist test equipment and industry-recognised methods:

• Continuity testing and fault localisation

• Insulation resistance (IR) testing

• Dead and live circuit testing

• Component-level diagnostics of MCBs, fuses, IGBTs and semiconductors

• Verification against relevant railway and electrical standards

Traction Control, VFD, Semiconductor & Power Electronics Support

We specialise in diagnosing traction control systems and variable frequency drives, vacuum fluorescent display modules, including obsolete and discontinued units, helping avoid unnecessary full system replacement.

Legacy & Obsolete Railway Electrical Systems

Rather than defaulting to replacement, we apply sound engineering judgement to extend the service life of legacy and heritage electrical systems cost-effectively.

‍

Electrical Remedial Works & Verification

Following diagnosis, we undertake or support remedial works, supported by verification testing and clear documentation.

• Replacement of defective MCBs and fuses  

• Rectification of damaged or poor terminations

• Replacement of broken conductors

• Functional verification and on-track testing
