- “I'll spend the day with you!”
- ―Duke to his passengers
A Special Story About Duke is a short rhyming magazine story.
Many years ago, Duke pulled the 'Picnic Train' and dropped the locals wherever they liked. One sunny afternoon, Duke passes a waterfall where everyone gets off the train to cool off in its pool. Duke decides that, since there is no-one left in his carriages, he will spend the day at the waterfall, too. His driver is happy as he too puts on his swimming gear.
- In the final illustration, Duke does not appear to be on the rails.
