Hello, my name is Paul and I am involved with a project to digitally map all the class one railways, street railways and inter-urbans, tramways or industrial service rails… in short anything that rides or rode on rails in southern Ontario. Please visit or website to view a sample of our work and download an always free copy of our map: http://individual.utoronto.ca/sorailmap/  . How to run and read the map is all covered on the website.
  I am writing you today in regards to the Sarnia street railway. I am currently mapping its routes and am seeking a map that details the line in its greatest form. I have been to the Sarnia public library and the Lambton room archives in Wyoming and have found varying oral recounts of where the lines went but no definitve map. Are you aware of such a map?
  We also seek yard maps, roundhouse and service facilities diagrams, sidings ectcetera of a historical nature for all mainline and branch operations such as Oil Springs etcetera.
  Also needed is a map of the Chatham Wallaceburg and Lake Erie railway and its spur to Pain Court.
  Any help we recieve is credited on our website and the information will be used to create what we believe is the most comprehensive
map ever created on this subject. I hope you can help.
 
  Regards,
