The train positioning technologies in urban rail transit are analyzed. According to the characteristic that train runs circularly along fixed rail track, train positioning technology based on absolute position encoding is proposed to the closed-loop track railway in urban rail transit. The single biconditional marker, whose value is 0 or 1, is placed on each position of rail track.

The Cambodia armoured train seems to have been used to patrol the narrow gauge line between Phnom Penh and Poipet during the war with Thailand although it didn't see any action. Both of them survived until 1945 but nothing else is known about these trains.

驻柬埔寨的装甲列车在和暹罗交战期间在金边和波贝窄轨上巡逻，但没有参加任何战斗。2辆列车一直服役到1945年，不过有关这些装甲列车的其他情况还不是很清楚。

To solve the aerodynamic problems resulted from high-speed trains when they pass through a tunnel, a model experiment system for high-speed trains was set up on the basis of analyzing the relative present experiment systems at home and abroad, and its similarity rules were derived. In this system, compressed air is used to impel a model train, and the speed of this train speed can reach 70 m/s.

为了解决高速列车进出隧道引起的空气动力学问题，基于对目前国内外高速列车模型试验研究现状的分析，建立了模型列车速度可达100 m/s的压缩空气式高速列车模型试验系统，并导出了模型试验的相似准则。
