A connect and disconnect assembly may have a first rotatable shaft and a second rotatable shaft aligned along a rotational axis. The assembly may also have a connect and disconnect device including one or more cams for selectively connecting and disconnecting the first rotatable shaft to and from the second rotatable shaft. A ship-lift bogie may include the connect and disconnect assembly.

Methods and means for reconfiguring an aircraft assembly plant that receives fuselages or fuselage sections via a public railroad system. In cases where the aircraft assembly plant comprises a first assembly line for installing (i.e., stuffing) equipment inside fuselages or fuselage sections and a second assembly line for installing equipment on exteriors of internally equipped fuselages or fuselage sections, both assembly lines being housed in the same building, the facility can be reconfigured by moving at least one fuselage stuffing operation of the first assembly line to an auxiliary building which overlies a railroad track connected to the public railroad system. The moved fuselage stuffing operations will be performed inside the auxiliary building while each fuselage or fuselage section is supported in an upright position on a respective railroad flat car.
