Feeding buffers are belt-driven conveyors used to either transport carriers between lines on a bridge, or used to transport carriers internally on a station (or between middle stations). The feeding buffer will use motors to pull carriers along instead of relying on gravity.
The feeding buffer status page will show the status of the motors in the group and if they have a status like motor overload or emergency stop.
With the correct permission, feeding buffers may be reset, started or stopped via the controls on this page.
For lines the corresponding page is Line Status.
