Primary Spring Chevrons - 09 HOPL (Victoria Line)

This direct award procurement is for the supply of the bogie Primary Spring Chevrons for the Victoria Line fleet.

The primary suspension chevrons are Metalastik units made up of metal plates bonded with a moulded rubber layer. This rubber serves a dual purpose: it acts as a spring while also providing damping, and it allows limited movement so the wheelset can make small rotations in all directions.

The programme is phase 2 of the of the Victoria Line Heavy Overhaul programme. This phase will commence in October 2026.

The Chevrons will be fitted to the Bogies at Depot with a 100% mandatory swap out of 128 Chevron per train. 46 trains will be overhauled in total. The train overhaul is being undertaken by TFL engineering team.
