Classification Yard Rush — Babylon Edition.
The inbound train rolls through the top of the yard. Tap a car on the train to grab it (it detaches), then tap a track to classify it there.
Each track's destination panel shows color + cargo type. A train needs an ENGINE first and a CABOOSE last, with ≥2 matched cars between. Fill a track and it ships out for points.
Beat the clock. Miss-classified cars = penalties.
