Oil was poured into the lower part of the journal box, which was loosely packed with cotton waste positioned so that it wicked lubricating oil onto the lower half of the axle journal, thus providing continuous lubrication. The workmen who added oil to the journal boxes had hook-like tools which would fluff up and reposition the cotton waste packing. Eventually, however, the waste would pack down and accumulate dirt, so it had to be changed periodically, usually about once a year. This is what was meant by journal repacking and, because it was required at more or less regular intervals, that's why the repacking data was stenciled on the cars. Journals were also repacked, of course, if a wheel set had to be changed out or if one or more journal bearings required replacement.
