The citizens soon welcomed the new service, and the social and cultural impact was significant. The Medellín Metro soon became a symbol of the city (it was the first, and still the only, rail-based Metro system in Colombia) which encouraged tourism and new business growth in areas of the city. There were visitors first from other regions and cities of Colombia and afterwards from abroad. Importantly, the metro bridged previously disparate poor urban and wealthy urban areas. The Metro passes through districts with widely varied socio-economic compositions. For example, it passes through both "Lovaina" and "Poblado".
