the TC/1000, squaring off the corners of the roofline. The TC/1000 was not a large success, competing against less-expensive school buses derived from van chassis; the model line was phased out after 1999 production. While Blue Bird has not produced a successor model line, the squared-off roofline returned in the design of the 2010-2013 All American. Commercial derivatives Alongside the All American, the TC/2000 (and TC/1000) served as the donor platform for several Blue Bird commercial buses during the 1990s. Using the same body as the school bus, the APC 2000 was designed with a variety of different seating types as well as interior luggage storage. Geared more towards transit and shuttle use (in line with the Q-Bus), the CS featured a number of exterior modifications to the body; a TransShuttle version based on the TC/1000 was designed with an optional central-mounted door. In addition to fully built buses, Blue Bird produced the CS as a "shell vehicle"; it was a bare body without windows or an interior intended for purchase to be converted into various types of specialty vehicles. In addition to transit-oriented buses, Blue Bird also produced the CS/APC and TC/2000 for use in law enforcement. While typically utilized as prisoner transports, some variants were also outfitted as mobile command centers.
