You Can't Win

You Can't Win is the fourth episode of the fourth season.

Plot
Duke is feeling poorly and Stuart jokes that he may have to keep him in order. Duke pays no attention, but when he's taking his passengers home he starts wheezing and Falcon and Stuart have to help him. The three split up at the next station so Falcon can take Duke's train to the dock and Duke and Stuart can take Falcon's train home. Stuart is delighted, but Duke isn't quite out of steam and makes a grand effort. At the top station a man tells his son Duke had to help Stuart, who furiously disappears in a cloud of steam.
