A new uniform has been launched by Transport for London (TfL) in the hope that it will help passengers recognise London Underground and Overground staff more easily. 

This comes as part of the organisation's wider efforts to improve customer service, which includes providing additional training for members of staff. 

A successful six-week trial for the new uniforms was carried out last year, which led TfL to the decision to introduce them permanently. 

The famous TfL Roundel - one of the most recognised brand icons in the world - appears on pockets, jacket cuffs, and the back of the uniform, as well as on small zip pulls.

Chief operating officer of London Underground Nick Brown said: "This new modern uniform ... reflects both our heritage and our diversity. The new designs will help give our customers an even better service by making our staff instantly recognisable to them."
