While transilenio is certainly over capacity on certain routes a metro wouldn't solve that problem. The real issue is that portals don't connect requiring riders to take circuitous routes thus over loading the system. Metros around the world are over capacity and are looking towards buses to solve this issue. Transmilenio has ridership of over 40,000 per hour along certain routes and that number could be lower with better administration and more feeder routes and another trunk route for a significantly lower price. Walk underneath or around the Medellin metro and you won't see development unlike the transmilenio which boasts pleasant vibrant spaces around many stations.
