TFL INSPECTION: Retrofitting of London TX4 taxis moves closer to final testing stage

HJS Emissions Technology has announced that Transport for London (TfL) is now inspecting the TX4 taxi, a move that could soon see the vehicle enter the final 5,000 miles of durability testing.

The milestone, shared via social media, signals that the retrofitting programme is progressing.

This development follows successful tests at Millbrook Proving Ground earlier this year. It represents a crucial step towards helping older diesel taxis, such as the TX4, meet Euro 6 emissions standards.

For many taxi drivers, retrofitting could be an attractive option. By upgrading their existing vehicles, drivers can avoid the expense of purchasing a new taxi while still adhering to tighter emissions regulations. This approach not only helps drivers extend the lifespan of their black cabs but also allows them to continue working without the financial strain of investing in new vehicles.

The initiative is expected to appeal to drivers looking for a more affordable route to maintaining compliance and extending their working life in an increasingly regulated market.

A HJS Emissions Technology spokesperson said on social media yesterday: “TX4 Being inspected by TfL today! We hope to be commencing the final stage of 5,000 miles durability testing shortly... Watch this space…”
