摘　　要：论述了2种提速列车的安全防护方案:与四显示自动闭塞配套的连续式列车速度监督方案及在三显示自动闭塞基础上增加应答器的点式列车速度监督方案。连续式ATP方案适合干线采用。点式ATP方案在提速列车数较少时最经济实用。The two schemes of safety protection for the speed-increased trains, i.e. the scheme of the continued type train speed supervision accompanied with the four-aspect automatic block and that of the point type train speed supervision with the responser added on the basis of the three-aspect automatic block are elaborated. The continued type ATP scheme is suitable for the main lines, while the point type ATP scheme is economical and practical in the cases when there are less numbers of speed-increased trains.
