The 20-year-old rail enthusiast was travelling home from a hospital appointment in London on board the Gatwick Express when he was given the chance to tell passengers where the train would be stopping.
Price shared a video of Harvey on Instagram captioned: "Harvey’s dream came true today doing a announcement on the @gatwickexpress going home after his hospital appointment."
Harvey is shown talking into the radio held up for him by the train guard saying: "Hello welcome aboard the Gatwick Express from London Victoria to Brighton via Gatwick Airport. My name is Harvey Price."
Price can be heard telling him what to say, adding: "And I'll be looking after you."
Harvey says: "Mummy looks after you."
Harvey - who has Prader-Willi syndrome, partial blindness and severe autism - revealed his trainspotting hobby in BBC documentary Katie Price: Harvey & Me.
As a result Network Rail offered to let him work as a station announcement maker for a day.
Price told Community Living magazine: "On the back of it, the BBC have offered Harvey and his friend Zack an eight-part series on trains and automobiles.
"There will be some gorgeous trains like the Bluebell Railway.
"I am not interested in bloody trains. Me and Jeanette [Zack’s mother] will be sitting there having our tea and sandwiches saying, ‘What are we bloody doing here on a train station?’ But, as long as they are happy, that’s what matters.”
The Bluebell Railway is a steam railway in Sussex, one or several preserved heritage lines around the country.
