A Special Story About Henrietta is a rhyming magazine story.
While everyone is working at the quarry, Henrietta just has to sit on a siding and wait wishing she could do some extra work.
Then, one day, a man and a dog are trapped and need help. Luckily, Henrietta hears their calls and alerts Toby. So, Toby and his faithful coach rush off to collect a doctor and a vet. Later, everyone declares that Henrietta is the brightest tram coach they have ever met.
