In January, 1967, the Children’s Zoo at Celebration Square introduced a new attraction: a miniature train. This brand new train was purchased from the Allan Herschell Company and is model number S-24, also known as the "Iron Horse". The Iron Horse is a miniature train designed to carry a larger number of passengers per trip than prior park trains. Its cars have colorfully painted canopies to protect riders from the sun. Each car is 17 feet long and can carry up to 14 adults. The engine was designed to resemble vintage locomotives of the 1870s. The same type of train was shipped all over the world to locations in Toronto, Canada, São Paulo, Brazil, Tokyo, Japan, and Barcelona, Spain.
The zoo would not have been able to make this purchase without funds from Dr. Carl H. Iberschoff, a Saginaw school teacher, who left the money to the city of Saginaw for improvement of parks and playgrounds. The train is affectionately called the Iberschoff Special, in memory of Dr. Iberschoff's generosity.
The Iberschoff Special is brightly painted in red and black and comes fully equipped with brass fittings, including a bell and a whistle to greet park animals and visitors. The Train ride quickly became, and has remained, one of the most popular attractions at the Children's Zoo. The Iberschoff Special has run faithfully for over 45 years despite increasing challenges in its maintenance.
