B23-7型柴油机车是美国通用电气公司在1977年推出的一款电力传动柴油机车,属于通用电气Dash 7系列柴油机车产品系列之一,主要竞争对象是易安迪公司的GP38-2型和GP39-2型柴油机车。
1977年,通用电气公司向市场推出新一代的Dash 7系列柴油机车,取代了自1950年代开始销售的通用系列柴油机车。该系列的改进重点是提高机车的牵引性能及燃油经济性,产品目录中的九种基本车型的功率等级涵盖1800马力到3600马力,B23-7型柴油机车即为其中之一。B23-7型柴油机车的名称代表着这是一款功率等级为2300马力、机车轴式为Bo-Bo的Dash 7系列车型,该型机车是C23-7型柴油机车(因没有铁路公司订购而从未投产)的六轴版本,并作为取代U23B型柴油机车的换代车型。1977年9月至1984年12月,通用电气公司和旗下在巴西的分公司共制造了537台B23-7型柴油机车。美国本土的主要用户包括聯合鐵路、密苏里太平洋铁路(英语:Missouri Pacific Railroad)、圣塔菲铁路、南方铁路(英语:Southern Railway (U.S.))、海岸沿海铁路(英语:Seaboard Coast Line Railroad)、南太平洋铁路、路易斯维尔和纳什维尔铁路(英语:Louisville and Nashville Railroad)等。此外,B23-7型柴油机车还被出口至墨西哥國家鐵路和东南联合铁路(英语:Ferrocarriles Unidos del Sureste)等海外用户。
B23-7型柴油机车是2300马力的干线货运用四轴柴油机车,采用单司机室、底架承载结构、双侧外走廊的罩式车体,车钩中心线间距为62英尺2英寸(18,948毫米),车体宽度为10英尺3¼英寸(3,130毫米),车体高度为15英尺6英寸(4,724毫米)。机车车体从前端到后端依次分别为司机室、电气控制室、动力室和冷却室。机车走行部标准配置为两台FB-2型二轴浮动摇枕转向架,采用导框式轴箱定位、大直径心盘牵引装置、两系弹簧悬挂装置(一系为轴箱螺旋圆弹簧,二系为橡胶堆旁承)和单侧闸瓦制动装置。机车装用一台12气缸、四冲程、V型结构、直接喷射、废气涡轮增压的通用电气7FDL-12型柴油机。传动系统采用交—直流电传动,柴油机直接驱动一台三相交流同步牵引发电机,发出的交流电通过硅整流装置转换为直流电,然后供给四台GE 752AF型直流牵引电动机。牵引电动机采用轴悬式驱动方式,牵引齿轮传动比为4.11(74:18)。机车设有由恒功率励磁控制系统(Constant Horsepower Excitation Control,CHEC)和“警哨”粘着控制系统(Sentry adhesion control system)所组成的模拟电子控制系统。
