Percy Gets Jammed is a magazine story.
Percy was shunting trucks in the yards. The stationmaster came running towards him and told Percy's driver that James' brakes had jammed as he was taking a truck of fruit to market. Percy laughed at James' misfortune but James was not happy. There was no time to turn Percy around so he has to push the truck. But the buffers came into view as Percy was still giggling about James' jammed brakes. The truck smashed into the buffers, split open and fruit went everywhere. The Fat Controller was very cross with Percy. James thinks it serves Percy right for being cheeky and Percy knew that James was right.
