TfL TX4 Approval

We have applied for the TX4 in December 2017 and now we have acquired TfL PCO approval to supply the GasCab product for TX4’s in London.


To supply in London, all alternative technologies have to pass the TfL approval criteria.
This includes:

  • Documentation
  • Certification
  • A durability test drive in London
  • Visual inspections (0 – 5k – 10k miles)
  • Emission test results (before and after the Durability test)
