The Unofficial Website of the Algoma Eastern Railway preserved on the Internet Time Machine is a wonderful site for history of the AER. The site was run by the AER Heritage Group managed by Dale Wilson, John Morgan, Mike LeHoux a past councilor in the Town of Espanola. The Virtual Tour has some great reference images https://web.archive.org/web/20160314020604/http://www.magma.ca/~morcomp/tourindex.html

Unfortunately many of the photos cannot be loaded but there is some interesting information here. I would love to get to talk to the websites owners one day. I’d be happy to help get this site running again.
