These colorful buses, known as Diablos Rojos, are a dying breed. Diablo rojos (Red Devils in English) are old school buses converted into city buses. Each one boasts its own unique, custom paint job with bright, usually red, colored murals on the outside. This culturally identifiable trademark is soon to be a thing of the past. They have been replaced with the more modern Metro Bus system. In Panama City alone, over 700,000 people use public transportation. The new buses are designed to carry about 80 passengers each – 30 sitting and 50 standing, which is about 25% more than what the Diablo Rojos can handle.
