Some European cities may give away or sell second-hand trams in order to modernize their public transport fleets or get rid of old vehicles. On the other hand, by acquiring second-hand trams, other cities not only buy still working vehicles at reasonable prices but also invest in the image of ‘green’ and modern public transport. However, this migration of trams may gain a neo-colonial air when the developed West profits from discarding old vehicles to the developing East. But, making use of the durability of tram cars, which may easily be operated for forty to fifty years, is a sustainable way to utilize public transport infrastructure.
