Stepney is enjoying his visit to the North Western Railway and offers to help Percy with his goods trains. After delivering loaded trucks to the harbour, Stepney goes past a cricket field with some "empties" when a batter hits a "six" and their only ball lands in a truck. Stepney does not realise this and when his driver sees Caroline chasing after them with the desperate cricketers inside, he mistakes them for joyriders and speeds up, much to Caroline's annoyance as she easily overheats when travelling at high speed. At last after being forced over a hill, Caroline arrives at the station and the men get their ball back, but Stepney's driver notes Caroline looks exhausted and suggests that she be rolled onto a flatbed so she can rest during the return journey. The cricketers ride back in a brake van and Stepney, his crew and Caroline watch the end of the game.

After Percy arrives with his trucks, his roof is lifted.
As Stepney arrives at Knapford Harbour, Thomas is seen leaving with some trucks, but he was still at Tidmouth Sheds when Stepney left. Also, his first truck derails before it goes off screen.
Studio equipment is visible in the shots of the cricket field.
