Bring back the signature car
Capn’ Cattlehammer operates the train from the inverted-pyramid control point. Send it outside, couple the first and second cars, then return those cars to the yard. Download the digital signature from the flashing car. Leave the later cars behind: the author specifically warns of a lethal hazard in the third car.
Identify the pickup and carriage
Vergusha’s repair-yard account identifies an evacuation robot to scan for the spider transmitter. It places the signature in the second carriage and describes the returned carriage as black with red flashing lights. This supports the first-two-car route; it does not establish that later carriages are safe.
