The near north side of Pittsburgh was liberally laced with streetcar lines. Here the 13, 14 and 15 came east on North Av to meet the 8, 21 and terminating routes 22 and 77/54 on Federal St. A block behind me were the 10, 11 and (at one time) 12.
Pittsburgh no longer has commuter trains and Johnstown no longer has trolleys, but light rail remains strong in Pittsburgh. Mr. Rogers would be pleased.
