1981 GMC RTS-04 Mega prototype


1977-87 GMC RTS

GMC manufactured the original Rapid Transit Series (RTS) bus starting in 1977. It was available in lengths of 30, 35 and 40 feet. It had actually began its life as an entry into the Advanced Design Bus project. It turned out to be GM’s final series of buses.

The earlier versions had a slanted back (previous image) which was squared up on the fourth series, from 1981 to 1986, to fit a larger A/C unit. GMC sold the RTS design and patent rights to Transportation Manufacturing Corporation (TMC), in May of 1987.

In 1981, GMC had produced the RTS-04 Mega prototype equipped with an articulating rear portion to allow for even greater lengths. Four were built in three sizes, at 55, 60 and 65 feet long (two at 60 feet). Although articulation would have been new to the RTS line, the feature had been in use in other countries since the early 20th century. One example from 1960, in Budapest, was capable of carrying 200 passengers.
