The penultimate station on the little known Glutton Valley Railway is Glutton Magna. Beside the station is the famous Sweetfeast's Treacle Pudding factory, from which enticing and mouth-watering aromas waft seductively across the surrounding countryside. Although this train is ready to leave the station, and the guard has repeatedly waved his green flag and blown his whistle, it cannot do so until the driver has hurried back from the factory with his weekly supply of puddings. There seems to be trouble with the valve on a treacle tanker in the siding, the amber flow no doubt making a particularly soggy mess when it meets the flour from a burst sack.
