Lucky little Tallulah Calvert became the one millionth passenger to ride the latest Scenic Railway on Monday.
The landmark came just over a year after the launch of the redeveloped attraction in April 2013, which saw the fifth train commissioned to travel the iconic incline railway.
Tallulah's name was announced during the train's descent into the Jamison Valley. She won a commemorative gift pack, which included a family annual pass and the coveted front seat for the return journey.
Tallulah was a first-time visitor to the Mountains, travelling with her parents and sister.
"I loved going through the dark tunnel on the cliffhanger train ride. It was lots and lots of fun," she said.
Joint managing directors it's a significant milestone for the family-owned tourism business just one year after its $30 million upgrade.
"Almost 70 years ago our grandfather opened Scenic World, inspired by the curiosity of visitors to the Blue Mountains and the steep railway into the rainforest," Ms Hammon said.
"This celebration is about the new era of the Scenic Railway."
