  • Six bearings above the 50 K alarm line

Debrief

Cars were matched to the waybill list by reporting mark, read from the daylight frame.

Findings were split by railroad so each carrier got its own bad-order list.

Three hundred and forty cars in forty minutes. The car inspectors start at the eight that matter.
