The last sections of electric staff working on Sydney Trains network were recently decommissioned. As part of this process, Sydney Trains commissioned an oral history on the use of electric staff. This resulted in a 36 page booklet and a 17 minute video, both of which are accessible from http://www.sydneytrains.info/about/heritage/oral_history
The comment has been made that it is an 'oral history' (i.e. some facts aren't), but it is of interest.
