Procurement of Air Springs for 09TS

Description

This direct award procurement is for the supply of the bogie air springs for the Victoria Line 09TS fleet. The air spring is a safety‑critical component forming the secondary suspension of the train, directly influencing ride quality, passenger comfort, dynamic stability, and compliance with the kinematic gauge under all operating conditions. The component was originally designed and manufactured by ContiTech to bespoke specifications provided by the train builder, Alstom. Its design incorporates proprietary rubber formulations and unique manufacturing processes that are protected as trade secrets and not available to third parties. As a result, only the original equipment manufacturer and its authorised distributor, Dellner Ferrabyrne Limited, can supply fully compatible parts. Procurement of genuine OEM air springs ensures technical compliance, mitigates safety risks, and supports the continued safe operation and maintenance of the Victoria Line 09TS fleet. ## Contract award Title: Supply of Air Springs for 09TS Victoria Line
