Bad order

nounShop talkRailroad

A car or locomotive with a defect that keeps it from running until it is repaired.

A carman or crew member who finds a defect, such as a cracked wheel, a broken safety appliance or a bad brake valve, tags the car as a bad order, and it must be repaired in place or set out to a repair track. The phrase works as a noun, an adjective and a verb: crews bad-order cars, set out bad orders and track a bad-order count that measures a yard's repair backlog. Railroaders use it loosely too, for a broken radio, a dead truck or a bad knee.

Heard on the job

Bad order that hopper for a busted grab iron and set it out on the rip track before we pull.

Insider tip

Railroaders say a car is bad-ordered the way other trades say a machine is tagged out.
