Production  Description 

The Railway Passenger Trailer Bogie is a high-performance two-axle bogie system purpose-engineered for metro train applications, designed to deliver superior ride comfort, reliable braking performance, and excellent curve negotiation capability in urban rail environments.

As a trailer bogie, this system is designed for non-powered applications—it does not contain traction motors—making it ideal for use in intermediate metro car positions where power is not required. This design reduces weight and simplifies maintenance while maintaining the structural integrity and suspension performance required for daily metro service.

Manufactured to meet international railway standards including AAR M-201 and EN 13103, this bogie is designed for maximum speeds up to 90–120 km/h and axle loads up to 14–16 tonnes, making it suitable for standard metro and light rail applications.

1. Fully Customizable Configuration

Each bogie is engineered to your exact specifications:

2. Superior Ride Quality

• Advanced Suspension Design: Primary suspension with metal-rubber springs or cylindrical coil springs with vertical hydraulic shock absorbers; secondary suspension featuring air springs with anti-roll torsion bars for superior stability 

• Vibration & Noise Reduction: Engineered to minimize transmission of track irregularities to the passenger cabin

• Semi-Active Suspension Option: Available with lateral semi-active dampers for optimized ride performance across varying track conditions 

3. Proven Engineering & Safety

• Finite Element Analysis (FEA): Every frame is subjected to rigorous stress analysis and fatigue testing 

• International Certification: Manufactured to AAR, IRIS, ISO9001, ISO14001, OHSAS18001, TSI, and other international standards 

• Design Life: Engineered for 3+ million kilometers or 30 years of service 

4. Low Lifecycle Cost

• Reduced Maintenance: Durable construction minimizes downtime

• Component Interchangeability: Standard parts used wherever possible for ease of maintenance

• Energy Efficiency: Lightweight design options reduce energy consumption
