Evidence from The Parcel in the Wrong Car

The swapped parcel caused an unexplained record at Rail Operations. Restore six logged moments to determine when the torn twine became decisive.

Logged events

  • Swapped parcel review beginsRail Operations staff open the case log for the swapped parcel.
  • Freight reader registersThe freight reader records a new signal.
  • Torn twine is locatedInvestigators log the torn twine beside the active area.
  • Coupling gate changes stateThe coupling gate moves to a different setting.
  • Manifest mark is confirmedThe manifest mark provides the decisive cross-check.
  • Routing lock is recordedThe routing lock marks the case record complete.

Exact clues

  1. “The torn twine is located” was immediately before “The coupling gate changes state”.
  2. “The manifest mark is confirmed” was not second.
  3. “The freight reader registers” and “The coupling gate changes state” were 2 positions apart.
  4. “The manifest mark is confirmed” was fifth.
  5. “The swapped parcel review begins” and “The coupling gate changes state” were 3 positions apart.
  6. “The manifest mark is confirmed” was before “The routing lock is recorded”.
Read the closed-case resolution

The manifest mark could only be confirmed after the coupling gate changed state. That places the freight reader before the torn twine, showing why the routing lock closed the swapped parcel case.
