The locomotive "Karácsony" is the jewel of the railway. In 1997, Kaszó Erdőgazdaság Zartkörűen Működő Reszvénytársaság bought the steam locomotive, which was manufactured in Resica in 1954 and renovated in Szászrégen in 1984. The locomotive, named "Karácsony", arrived in Kaszó on December 14, 1997 and was put into service on April 16, 1998. It is still used occasionally today.
