一、结合实际，制定规划安全是铁路运输的生命线。在现代化铁路运输中，仅靠人的精力、觉悟来维持行车安全是不够的，必需依靠科技进步，采用先进的技术设备，把行车安全建立在更加可靠的基础上。电务设备投资少、安全好、效率高。联锁关系越完备，车务、机务部门的责任事故就越少，运输综合效益就越高。 First, with the actual planning and development is the lifeblood of railway transport. In modern railway transportation, it is not enough to rely solely on human energy and consciousness to maintain traffic safety. We must rely on scientific and technological progress and adopt advanced technical equipment to establish driving safety on a more reliable basis. Less investment in electrical equipment, safety, high efficiency. The more complete the interlocking relationship, the less accidental accidents will occur in the vehicle and maintenance departments and the higher the overall efficiency of transportation will be.
