The Brecknell Willis High Reach pantograph is one of the four standard pantographs in use on British railway locomotives and multiple units. In 1973 the small West Country firm of Brecknell, Willis & Co. patented a very compact and ingenious design of single arm pantograph. This was a development of an idea from Doug Dixon, a consultant designer to BW & Co. The Highreach pantograph formed the basis of the BR/Brecknell Willis High Speed pantograph which was a joint development between Brecknell, Willis and BR Research & Development Department during the late 1970s.
