Modernization of diesel locomotives

About the Company

Since 2010, Prombudkoliya has been carrying out modernization of diesel locomotives and industrial locomotives in accordance with modern efficiency and safety standards. We implement advanced technological solutions that increase productivity, fuel efficiency, and reliability of locomotive fleets for industrial enterprises and transport companies.

Modernization is performed at our own repair facilities using certified equipment and components. All work is carried out in compliance with Ukrzaliznytsia requirements, DBN regulations, and international ISO 9001 standards.

Objectives of Locomotive Modernization

Modernization extends the service life of a locomotive by 10–20 years, reduces operating costs, improves fuel efficiency, and enhances driver comfort. After upgrading, the locomotive meets current environmental, safety, and energy-efficiency requirements.

Main Areas of Modernization

Power Unit Modernization

Replacement ("repowering") or major overhaul of the diesel engine with the installation of more efficient and environmentally friendly power units. Electronic fuel injection control systems, new generators, compressors, and cooling systems can be installed. This ensures reduced fuel consumption and extended engine service life.

Electrical System Upgrade

Modernization of generators, starters, wiring, batteries, and control systems. Installation of new control panels and protective devices, as well as transition to modern automated monitoring and diagnostic systems.

Control Desk and Driver’s Cab Reconstruction

Installation of modern control desks with digital displays, video monitoring systems, air conditioning, and improved lighting. Cab ergonomics and sound insulation are upgraded to enhance operator comfort.

Brake System Modernization

Replacement of outdated pneumatic system components with modern electronically controlled modules, installation of new compressors, air reservoirs, and pressure regulators. Brake reliability and control accuracy are significantly improved.

Running Gear Reconstruction

Restoration of bogies, installation of new bearings, suspension springs, axleboxes, and brake components. This improves stability, ride smoothness, and reduces wheelset wear.

Bodywork and Exterior Upgrade

Abrasive blasting, anti-corrosion treatment, repainting, and application of corporate livery. Replacement of cable routes, exterior lighting, and impact-protection elements may also be performed.

Modernization Stages

Diagnostics and technical inspection of the locomotive
Development of a modernization project and technical documentation
Removal of obsolete assemblies and components
Installation of new equipment and systems
Testing, adjustment, and running-in
Handover of the locomotive with completed documentation and certificates

Completed Project Examples

Modernization of a TEM2 Diesel Locomotive (Dnipro, 2023)

The D50 diesel engine was replaced with an electronically controlled power unit; the generator and brake system were upgraded, and new control panels and an air-conditioning system were installed in the cab. Fuel consumption was reduced by 18%.

Comprehensive Modernization of a ChME3 Locomotive (Poltava Region, 2022)

Modernization of the diesel engine, bogies, and electrical systems was completed. A new driver’s cab and onboard diagnostic system were installed. The locomotive now complies with modern environmental standards.

Reconstruction of a TGM6A Locomotive (Zaporizhzhia, 2021)

The brake system and electrical equipment were replaced, the body was refurbished, and new axleboxes were installed. After testing, the locomotive was commissioned with an extended service life.

Frequently Asked Questions

What is the typical duration of locomotive modernization?

On average, from 30 to 90 days, depending on the scope of work and the technical condition of the locomotive.

Is partial modernization possible?

Yes, modular modernization can be performed — for example, of the diesel engine, brake system, cab, or electrical equipment.

What benefits does modernization provide?

Fuel consumption reduction of up to 20%, increased power and reliability, extended service life, and improved working conditions for the locomotive driver.

Do you provide a warranty?

Yes, all completed work is covered by a warranty of up to 18 months, depending on the project, along with post-modernization technical support.
