no footnotes date October 2011 The Brecknell Willis High Speed Pantograph was designed during the late 1970s early 1980s by Brecknell Willis and British Rail Research Division as part of ongoing research into developing a pantograph capable of speeds over the 100 mph 160 km h of the as then standard Stone Faiveley AMBR pantograph . The research was mainly carried out at the Old Dalby Test Track in Leicestershire and then on the West Coast Main Line WCML . The WCML tests, between London and Preston, were initially done with the pantograph attached to the top of Laboratory Car 6 Prometheus test coach during December 1978. After some initial problems with these tests, the pantograph was modified at Derby Old Dalby but returned to WCML testing in July 1979 between London and Carlisle. After this testing, Lab 6 was moved to the East Coast Main Line for maximum height testing. The locomotive to be fitted with the pantograph was British Rail Class 86 Class 86 no. 86244 during February 1980 with a second locomotive, British Rail Class 87 Class 87 no. 87005 during late 1981. Testing was also carried out on the APT P during the development of the pantograph testing time. gallery File Acela overhead view.jpg Overhead view of the Brecknell Willis High Speed pantograph in action on the US Acela vehicle gallery Today The pantograph is the mainstay within the UK railway.

History in the UK 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 pantograph was primarily designed as a lightweight rapid transit pantograph where its compact size when folded, combined with its ability to reach up to high wire height, resulted in it being christened the Highreach pantograph . The pantograph was, in keeping with most pantographs at the time, spring operated with an elementary head suspension. It featured needle roller bearings at the base as well as cams and chains at the elbow. The operating rods were cleverly hidden inside the hollow arms making an excellent aesthetically pleasing design. The first mainline use in the UK of these were back in 1974 when a number were added to the British Rail Class 306 Class 306 Clacton Units based at Ilford. These continued to be used until around 1980 when they were all removed from mainline use. However the Highreach formed the basis of the Brecknell Willis High Speed Pantograph BR Brecknell Willis Highspeed pantograph Current users in the UK Manchester Metrolink T 68 original Manchester trams T 68 br Midland Metro Midland Metro rolling stock Midland Metro Trams br Supertram Sheffield Sheffield Supertram Siemens Duewag Supertram br Tyne and Wear Metro rolling stock br Photo Videos http www.youtube.com watch?v tJ6t92W7dMA Youtube clip of Tyne & Wear Metro pantograph raising during open day Category Tram technology Category Pantographs rail ... more details

Subsequent operation was by diesel locomotive . The railroad was closed in 1992. The Visalia Electric used the unusual choice of 15 Hertz Hz alternating current AC at 3,300 Volts carried by overhead wire , with pantograph rail pantograph s on the cars for pickup. Parent Southern Pacific intended this as a testbed for main line, long distance electrification of its own lines in the area, a project that never came to fruition. At one time in its life the Visalia Electric briefly interchanged with the Atchison, Topeka and Santa Fe Railway ATSF . The ATSF was seen by the Southern Pacific as a rival.
