"Whistles are for safety, not for playing games!"
―Sir Topham Hatt

Percy's New Whistle is the second episode of the eighth season.


Whilst delivering trucks to the quarry, Percy whistles a greeting to 'Arry and Bert who laugh at Percy's whistle. Percy is determined to show the diesels that his whistle is just as good as their horns. As Percy puffs through the countryside, he practices whistling loudly. Later, he goes back to the quarry and creeps up behind 'Arry and Bert. He blows a great toot on his whistle, which startles the two diesels.

Now that he has a super-loud whistle, Percy cannot wait to use it again. So when he sees Thomas in a siding, Percy blows a loud whistle again! Thomas jumps forwards and biffs into his trucks. Thomas ends up cross, but Percy does not notice because he is too busy having fun to notice. Later, when he sees Bertie, Percy lets off another loud whistle which sends a startled Bertie swerving across the road and into a snowy ditch. Bertie is cross as well, but Percy does not realise.

That evening, Thomas tells Percy about all the trouble he had caused that day. Percy is sorry for his actions but, the next day, while streaming through the countryside Percy wishes that he could have one last loud toot on his whistle. Although he does not see anyone about, what he does not know is that Trevor is delivering food to feed some sheep on the hill above. Percy’s loud whistle startles Trevor and he jolts backward and knocks a log down the hill. The log collects snow and turns into a giant snowball! When it reaches the bottom of the hill, the gigantic snowball collides with Percy.

Soon, Sir Topham Hatt arrives on board Thomas and angrily scolds Percy for inappropriately using his whistle. Percy promises to only use his whistle when the time is right. The next day, Percy is a very quiet engine. But, as he comes out of a tunnel, he spies a snowdrift on the line. Then, he hears Thomas approaching. Percy blows a warning whistle and Thomas grinds to a halt just in time! Percy is praised by Sir Topham Hatt and now only uses his whistle responsibly.
