一、序言联邦德国国营铁路于1985年6月2日改用新的“I C 85”城间客运时刻表,因而增加了对一等空调客车的需求量。为适应新的客运要求,13个月内在成批生产的Bpmz291.2和291.3型二等开敞式空调客车的基础上研制出7辆Apmz123型一等开敞式空调客车(图1)。设计方案中有很多零部件,如车体钢结构、供电、空调、走行部分、制动、牵引缓冲装置、侧门和通过台部分的平面布置以及许多内部设备均以Bpmz291型车为依据。
I. Preface The Federal German state-owned railway switched to the new “I C 85” intercity passenger timetable on June 2, 1985, thereby increasing the demand for first-class air-conditioned buses. To meet the new passenger requirements, seven Apmz123 first-class open air-conditioned buses (Figure 1) were developed in 13 months on a mass production basis of Bmiz 291.2 and 291.3 second-class open air-conditioned buses. There are many components in the design, such as the body structure of steel, power supply, air conditioning, running section, brake, traction buffer, side door and through the Taiwan part of the layout and many internal equipment are based on the Bpmz291 car.
