FLEXX Urban bogies

FLEXX Urban bogies are configured to ensure smooth and safe journeys for travelers in cities, thanks to specific design features.

Low noise, passenger comfort, robustness, reliability and a high level of safety are common characteristics of the FLEXX Urban bogie family.

More than 10,000 FLEXX Urban bogies are in successful operation beneath 3,000 FLEXITY trams in Berlin, Kassel, Basel, Toronto, Melbourne, Brussels and Marseille.

Environmental friendliness

FLEXX Urban bogies are perfectly integrated into vehicles to minimize the transmission of vibration and noise to the environment.

Easy accessibility

Trams and light rail vehicles are designed for ease of accessibility and convenience for urban travelers. FLEXX Urban bogies make these features possible through their compatibility with low floor levels.

Over 4,000 FLEXX Urban bogies are operating under 100 per cent low-floor vehicles.

FLEXX Urban bogies serve the complete range of trams and light rail vehicles, depending on customer needs: from 100 per cent low-floor city trams to dual-system trams, and for narrow- to standard-gauge networks.

Extended lifecycle

Particular attention is paid to maintenance aspects such as minimum rail and wheel wear, enabling long wheel lives.

A significant level of standardization answers market needs for high technical reliability, substantial reduction of lifecycle costs, long-term availability and reduction of delivery time for spare parts.

FLEXX Metro bogie 6048

FLEXX Metro bogies

Frequency and reliability are of the utmost importance for high-performance mass-transit systems. The FLEXX Metro bogie is crucial for metro trains in terms of safety, maintenance cost and passenger comfort. These requirements are met by extreme reliability, robustness and straightforward design.

Railway infrastructures are as varied as the cities they serve. For that reason, the FLEXX Metro portfolio reflects these distinctions with different configurations such as radial steering or inboard bearing designs.

More than 24,000 FLEXX Metro bogies are currently in service in Paris, Berlin, Stockholm, London, Bucharest and New Delhi.

Optimal safety

The robust design of FLEXX Metro bogies enables operations on networks with challenging track twists.

The FLEXX Metro bogie portfolio features several innovative design concepts including articulated frames for optimum safety against derailment, and guarantees safe journeys for passengers.

Low lifecycle costs

All FLEXX Metro bogie components are designed and specified with a view to reducing whole bogie lifecycle costs. Emphasis is placed on rapid and easy exchangeability of all components.

The design of the FLEXX Metro bogie family is characterized by maximum use of standard components. This ensures competitive cost levels as well as the use of proven design solutions.

Bogie maintenance is based on the principle of removable modules for operators’ convenience and for maximizing fleet availability. The number of wearing parts is minimized.

Environmental friendliness

FLEXX Metro bogies’ lightweight bogie concepts enable maximum vehicle capacity utilization with minimum energy consumption.

Primary suspension with elastomeric components gives excellent steering performance and guarantees minimal noise and vibration for the benefit of urban inhabitants and the comfort of passengers.

Bombardier FLEXX Eco bogie 6050

FLEXX Eco bogies

The FLEXX Eco bogie has been developed to satisfy customer requirements in terms of lifecycle costs and environmental considerations.

The success of the design arose from a fundamental re-think of the conventional bogie layout that retained and improved the overall safety and performance expected from a modern bogie design. The general simplicity of the design combined with the inboard bearing wheelset concept has resulted in a compact, lightweight and robust bogie.

FLEXX Eco bogies are currently being manufactured for the MOVIA C30 metro for the city of Stockholm, and for the INNOVIA metro trains for Riyadh, Saudi Arabia.

Train weight reduction

FLEXX Eco bogies optimize the overall performance and reliability of the vehicle by reducing the train weight. The bogie is compact and lightweight: 30 per cent reduction in weight bogie mass compared with a conventional bogie, and 25 per cent reduction in unsprung mass.

Improved total cost of ownership

The FLEXX Eco bogie reduces maintenance costs. Reductions are driven by easy access to the wheels and brakes thanks to its inboard bearing design resulting in total lifecycle costs that are as much as 25 per cent lower. Maintenance intervals are also extended significantly due to the lower unsprung mass of the FLEXX Eco bogie, leading to reduced wear on track. The compact design of the bogie reduces energy consumption.

Track friendliness

FLEXX Eco bogies enable safe and comfortable journeys for urban passengers. The specific design and low weight of the bogie reduce track damage. The bogie also reduces rail wear thanks to improved performance on curves.

Innovative mechatronic platform

Safety, efficiency and flexibility are guiding principles in Bombardier’s product development.

Four mechatronic solutions using a modular system with standard components have been developed and can be applied to the full portfolio of FLEXX Bogies:

  • FLEXX Tronic technology with ARS – active radial steering
  • FLEXX Track – track condition monitoring
  • FLEXX Guide – bogie condition monitoring
  • FLEXX Tronic WAKO – roll movement compensation

These four applications represent major customer benefits in terms of maintenance and costs.

FLEXX Tronic technology with active radial steering

FLEXX Tronic technology with active radial steering and stability control (ARS) installed on FLEXX Bogies allows the stability and curve-friendliness of the train and many other benefits:

  • Track-friendliness: diminution of track impact
  • Reduced maintenance costs: active system and self-diagnosis to anticipate the decrease of performance
  • Reduced noise and vibration: comfort improvement for passengers thanks to tilting


FLEXX Tronic technology can equip any FLEXX Bogies and can be used on different national track networks.

FLEXX Track – track condition monitoring

FLEXX Track is a sensor-based measurement system installed on the vehicle. It is designed to monitor track conditions and evaluate their deterioration over time.

The information obtained thanks to the FLEXX Track system is used to identify and locate track disturbances such as track torsion, vertical track disturbances, crushes at joints and switches, and rail ripples.

It is designed as a modular system and can be configured for various measurement requirements.

FLEXX Guide – bogie condition monitoring

FLEXX Guide is a monitoring systems in the bogie, dedicated to safety or maintenance.

The benefits for the operator include:

  • Avoidance of in-service failures
  • Improved maintenance scheduling
  • Maximized components’ lifetime
  • Increased safety

All systems are built up from components out of Bombardier’s mechatronic building blocks.

During development, attention was especially given to support a simple integration and easy retrofit.

FLEXX Tronic WAKO technology

FLEXX Tronic WAKO technology is an innovative mechatronic solution designed to compensate the natural roll movement of a carbody.

The system allows the vehicle to increase speed in curves by 15 per cent, enabling shorter journey times and improved punctuality with lower infrastructure investment.

The design principles enable a high comfort for passengers with no seasickness effect.

The self-diagnosis features lead to a high reliability, lower lifecycle costs and reduced maintenance costs for the trains.

FLEXX Tronic WAKO is currently in operation on the FLEXX Compact bogies of the TWINDEXX Express double-deck trains in Switzerland.
