According to Mr. Linder, the University Avenue Line in the Bronx ran from May 31, 1906 to October 26, 1947. The official number of the line was # 7 but thus never appeared on the cars. When the 1200 series cars were placed in service, the cars carried a large metal plate on the dashboard with the letter "U" and "University Avenue" written underneath. The line was originally a New York City Interborough Railway Company.
