热空气采暖客車的实例铁路客車利用热空气采暖已有30年历史。德国在1939年以前就有一些內燃机車使用热空气采暖,1938年約有10辆直达快車安装了各种热空气采暖装置,以便广泛地积累經驗。二次大战使这項試驗工作中断。战后五年,客車制造业中开始采用新設計以来,在客車采暖方面走上了另一条道路,尤其是对于用机車牵引的客車更为如此,因为这些客車大部分是新造的。只有少数客車,近年来安装了 Example of hot air heating passenger car Railway passenger car has been using hot air to heat for 30 years. In Germany, some diesel locomotives used hot-air heating before 1939. In 1938, about 10 direct express trains were equipped with various hot-air heating devices to gain extensive experience. World War II interrupted the pilot work. Five years after the war, the new design of the bus manufacturing industry has embarked on a different path towards passenger car heating, especially for buses towed by locomotives, as most of these buses are newly built. Only a few buses have been installed in recent years
