The Shuttle-C of the late 80’s/early 90’s would have carried a whole lot more to orbit than the Shuttle Orbiter, but would not have been quite as capable of precise maneuvering as the Orbiter. Consequently, it might get close to a space station, but it would be unlikely to dock with it unless it was moved into position with secondary orbital maneuvering vehicles or grabbed with manipulator arms. This artwork depicts a Shuttle-C standing off some distance from a space station, with the cargo being shuttled over with an OMV.
The Shuttle-C was described and illustrated in US Launch Vehicle Projects #4.
