In 1889, the first electronic street railway was introduced in Colorado by Denver Tramway. Their main competitor, The Denver City Cable Railway, built a cable car power plant with its iconic chimney the same year. However, their old technology was no match and they went bankrupt within a few years. Behind it is the 22 story 1800 Larimer Office Tower, one of Denver’s newest high-rise buildings. It opened in 2010 and houses Xcel Energy.
