Michael AS you noted in your original post, Saxby & Farmer later became founding parts of the Westinghouse Brake & Saxby Signal Co - the Saxby part of the name was dropped in 1935. I wanted to add to the other reply on here that a significant amount of historical documentation about the Company is held by the Chippenham Museum & Heritage Centre, which may be a better or at least equally important source than the Wiltshire & Swindon History Centre in Chippenham. It may be worth contacting them to enquire whether they have records of Saxby & Farmer or not. Unfortunately the book that details the history of WBS by the late O.S. Nock "A Hundred Years of Speed with Safety" covers "only" the period from 1881 which would post-date your ancestor's time, but may still be of interest. You may also find the following web site of interest: http://www.polunnio.co.uk/ as it covers history and associated publications of the constituent companies. I have no family connection with either company, apart from the fact that I worked for WBS (or Wes as it was often known) in Chippenham for many years and have always had an interest in the history of the company. My wife also worked in the Drawing Office, so I suppose I do have a family connection in that sense :-) Jon Baker -----Original Message----- I'm trying to trace anybody who had ancestors who work for the Saxby & Farmer Signal Works. John Saxby worked for the London, Brighton and South Coast Railway which began in 1852. In 1856 Saxby took out a patent for a signal lamp that was linked to the railways point and manufactured his new signals in Brighton but left the railway in 1862, moved to Kilburn in London where he joined forces with John Stinson Farmer and opened a factory in what was then Kilburn Lane and later became Canterbury Road. The company was amalgamated with others in 1920 to form Westinghouse Brake and Saxby Signal Company. My Gt. Gt Grandfather was pattern maker until his death in May 1871 Michael
