从燃料的消耗和安装设备上,可以估算客车采暖所需的费用。燃料费用的增加与机车效能的提高有直接关系。在蒸汽机车上,采暖所需的蒸汽为锅炉出量的5％或6％。在内燃机车上,用于采暖的燃料占牵引所需燃料的10％。在寒冷地带,这些数值还要大大增加。西德的电气化铁路采暖要占牵引能量的12.5～ From the fuel consumption and installation of equipment, you can estimate the cost of bus heating. The increase in fuel costs is directly related to the improvement of locomotive performance. In steam locomotives, the steam required for heating is 5% or 6% of the boiler output. In diesel locomotives, the fuel for heating accounts for 10% of the fuel required for traction. In the cold, these values ​​have increased dramatically. West Germany’s electric railway heating to account for the traction energy of 12.5 ~
