Pigeon Passengers is a magazine story.
Thomas spots some birds whilst parked in a siding by the Windmill, and his driver kindly shares his sandwiches with them. When Thomas stops at a signal, he tells Percy about the birds. Percy, who is being loaded with sacks of grain, teases Thomas. Then, a man drops a sack of grain all over Percy. A flock of hungry pigeons spot him and eat the grain.
