A modular manufacturing line includes first and second modular manufacturing stations. Each station includes a framework defining a manufacturing space, and an overhead friction drive system supported on the framework for moving a suspended article through the manufacturing space. A control system is in communication with each drive system and is configured to simultaneously control a first article at the first station according to one operation pattern and control a second article at the second station according to a different operation pattern. A work tool including a work tool spray nozzle is positioned at the first station and is movable along a floor mounted work tool support track. The first article moves through an article pathway volume that intersects with a work tool pathway volume defined by the work tool movement.
