Cable cars are transportation vehicles designed for carrying passengers or cargo and they serve the purpose of overcoming height differences. The construction, operation, and maintenance of cable cars require strict adherence to legal regulations, considering their purpose and execution method. Types of cable cars can be divided based on their purpose, execution method, or type of propulsion. Funiculars are a special type of cable cars that do not hang, but move on a fixed track or rails. In this paper, we will focus on the Cable Car Act and its associated regulations that govern this type of transportation. The main objective of the paper will be the analysis of the operation and maintenance of the Zagreb funicular. Through the paper, we will provide insight into the mechanical and electrical systems, their function and maintenance, with the aim of better understanding this type of transportation system. The images presented in the paper were taken by the author, while the diagrams were extracted from the project documentation. The paper will also include the author's suggestions for modernization.
