1936年春,刘少奇到天津主持北方局工作后,以批“左”为契机,将原北方局、河北省委出身的干部调离或外派。与此同时,他选拔了一批“一二·九”运动前后崭露头角的青年干部,重用一批通过营救而出狱的干部,使华北地下党的力量有所恢复。白区工作会议进一步确认了前期组织重整的结果。在中共中央与北方局的推动下,原河北省委中的部分地下党干部组成平汉线省委,从平津地区撤出。平汉线省委被赋予的任务不断变化,组织和人事安排也屡经改易。河北沦陷后,平汉线省委一度临崩解,但依靠其工作的灵活性及八路军的保护,平汉线省委的这批干部最终被保存下来。他们在晋冀鲁豫四省交界地区与本地干部及其他从平津撤出的干部结合起来,组建新的冀豫晋省委,形成晋冀鲁豫根据地的干部基底,实现了组织上的“异地转接”,迈出中国共产党在华北组织落地的关键一步。
