The tram system followed the innovative BOT (Build, Operate, Transfer) investment model, allowing the Belgian company to operate the system for a set period before transferring it to the government. This marked the beginning of organized public transportation in the city. Modernization also included improved transportation infrastructure. Before the tram system, the Ray railway line was built, connecting the capital to the ancient city of Ray. This railway, also constructed by the Belgian company, marked an early milestone transportation history.
