The use of training buses for practical training is especially popular among the Hong Kong franchised bus companies. In Hong Kong, training buses are known in Chinese as "訓練巴士" (pinyin: Xùn liàn bā Shì). Training buses used in Hong Kong, such as those used at Kowloon Motor Bus, are typically buses that are older buses and retired from its main bus fleet, therefore only used for training purposes and not for passenger services.
