I found this old postcard among Mom’s things. According to Wikipedia, “The Elgin and Belvidere Electric Company was a 36-mile (58 km) interurban line that connected Belvidere, Illinois and Elgin, Illinois.”

Wikipedia briefly mentions the strike, saying “[Bion J.] Arnold [the owner] himself was heavily involved in the line’s construction and management, and at one point operated the cars himself during a strike.”

I cannot find anything else about the wreck and strike on the Internet.
