The AAR does not allow the journal box lids so that the bearing caps can be inspected. Any loose or missing cap boly is an immediate defect.
The hole cut into face of the box is so that a detector can "see" the bearing to check for a hot bearing.
One of the disadvantages of roller vs. friction bearings is that any hard or long derailment requires that roller bearings be sent to a bearing shop for inspection/repair.
USG has run roller bearings since 1946 on their Western bottom dumps.
