Don't judge and engine by it's size

Don't Judge and Engine by its Size is the second episode in the second series of Miniature Railway Adventures.

It is in this story that we are introduced to Jean Anderson.

Plot
A troublesome derailment leads to Lady Grange being taken out of service. But Casey was already prepared for such an event. He announces that he has bought a new engine that will cover for Lady Grange whenever anything like this happens. Everyone is excited about the news and wonder what the engine looks like. Only when the engine arrives, it is far from what anyone expected. The new engine, whose name is Jean Anderson, is so small that even Puffa beats it in size, and is a laughing stock of the railway. Because of this Casey is ordered to only take 1 coach while carrying out his passenger runs, leaving Betty and Sir Gyles to take over the heavy duty trains.

However one afternoon, Puffa develops and electrical fault and is stranded at Mercade Pass with a long train of empty coaches for the coach sheds. The only engine available is Jean Anderson, but Cars thinks they'd better wait till another engine is spared. But Casey goes behind his back and steams off to the rescue. As soon as Jean is coupled to the train, Casey shows just how powerful Jean Anderson is. The little engine pulls the long train as easy as pie, much to the surprise of everyone.

After apologising about what they said, the society enlists Casey back into full passenger runs with Jean Anderson.
