The Toronto Star had an article (August 31, page R6) about school cars in northern Ontario. There is a post in the Ontario archives on the same subject at HTML: http://www.archives.gov.on.ca/english/exhibits/education/railway.htm . School cars were used in the isolated communities along the railways; they would be dropped on a siding and left for a week. when the cars left, students would be given 6 weeks of assignments to keep them until the car returned. They also served as a community center in the evening. A school car could be modelled with an old wooden coach lettered (just given a label or name) and put on a siding. There is a school coach museum in Clinton, Ont, in the last surviving car.
