Greater Manchester bus stops were replaced over a five-year period. The older bus stop flags were based on a nationally adopted design featuring a single decker bus and were used over the entire country with the exception of London. Following bus deregulation there was no compulsion to use the national symbol and several passenger transport executives like West Yorkshire Metro's Metro and Merseyside adopted a new bus stop flag design featuring their capital M logo. GMPTE inherited their own M shaped logo and also began to use it on the glass back of bus shelters from the late 1990s. They have subsequently introduced this to a new design for bus stop flags – firstly used in 2002 on high priority routes – and now being erected across the entire GMPTE area.
