|Season Three, Episode Fourteen|
|Air date||Thursday 5th April 2012|
Bad Water is the fourteenth episode of Season 3, and the thirty-second episode overall.
James returned to Tidmouth Sheds to find Alfred and Gordon arguing. Sir Charles Topham Hatt wanted to find out what's going on. He saw that Gordon and Alfred were arguing about an incident in 1923. He explained the story to the engines. Sir Topham Hatt I, Charles' father and the first controller of the North West Railway, had called all of his engines (Thomas, Edward, Henry, Winston and Alfred) to the sheds to meet a visitor, who turned out to be Gordon. The Fat Director (As he was nicknamed) wanted to see if Gordon could become the new express engine. He perfomed well with the morning's Wild Nor' Wester to Barrow-in-Furness.
On the way back, Gordon was passing through Crosby when the stationmaster flagged him down and told him that Henry had broken down at the next signal box. Meanwhile, Alfred had arrived at Knapford with a local passenger train. One of the passengers stepping off the train turned out to be Sir Nigel Gresley, Gordon's designer, who talked to Sir Topham Hatt about Gordon's trial. Just then, Gordon arrived with Henry, and Alfred became worried when he heard Sir Topham Hatt say he'd give Gresley a 4-6-0 as part payment for Gordon. Alfred spoke to Edward about his troubles later that day.
