There was an article in last Saturdays Toronto Star newspaper about schooling in remote areas in the 1920s. A train would drop the school car in a remote area and local children would get the opportunity for some education. The car had desks for 18 children. The teacher and his family lived in the other half of the car. After 4 or 5 days the car would be moved to another location. The children were left lots of homework to do before the car returned. It operated on a 240km stretch of track north of Sudbury Ontario.
