About the Bus Engineering team

The Bus Engineering team are responsible for the setting, monitoring and maintenance of bus engineering standards that bus operators must meet to satisfy TfL that all customers travelling on buses have safe and reliable vehicles.

They work in partnership with other authorised agencies to ensure the management of engineering quality monitoring programs are maintained with each individual bus operator to a consistently high quality in engineering standards.

They carry out the technical evaluation for a number of ongoing technology demonstration trials with the aim to deliver innovative and sustainable design solutions to introduce cleaner and emissions-free vehicles into the bus fleet.

Their other workstreams include providing regular fleet audit reports, maintenance of the London bus design and the technical specification documents (which define all bus-type build standards for the bus manufacturers).
