PURPOSE:To make railway track sketch map generating, revising, and updating operations more efficient. CONSTITUTION:Once an indicating means indicates a line section, a sketch map data constructing means reads out facility data regarding the indicated line section among facility data stored in a ...

Introduction To effectively use urban land and address various urban transport problems, in recent years the government of Taiwan has been promoting the use of elevated railway systems in urban areas,...
i.e. the railway car is of the self-propelled type, e.g. of the kind used on subways, elevated lines, suburban rail lines and both intra-urban and inter-urban rail lines in which the electric power may be picked up, for example, from a third rail paralleling the track or by a pan...
It is also possible without changing the final result of the process to use as the corrective element, instead of the measurement of the absolute return value of the track, that of the value of its relative return in relation to the desired alignment on XY, shown on the drawing by the va...

The 1:36 gradient between Ilfracombe and Mortehoe stations was one of the steepest sections of double track railway line in the country. In the days of steam traction, it was often necessary to double-head departing passenger trains. Named trains such as the Atlantic Coast Express and the ...
Studies performed at the rail track sections with rail dampers installed showed a reduction in noise from 4 to 6 dB(A), and vibration up to 9 dB (Benton 2006; Koller et al. 2012). Aside from rail noise, non-audible vibrations are also generated by the trains, transmitted via the ...
Meanwhile, the terrain features and track conditions were also key reasons for limiting the speed of HSR in Japan. Whereas, the land of Germany, Britain, and other Western countries was mostly privatized, which leads to high costs in the procedure of construction and hinders the development of ...
Based on an economic-cost analysis, it was determined that natural pozzolans (NP) were a suitable replacement for fly ash (FA) in the production of sustainable concrete for high-speed railway concrete slab track design. The results confirmed that the inclusion of DCA effectively improved the ...
When a car starts to traverse the stretch of track shown in the drawing, relay ITR will pick up first for reasons which will be apparent from the foregoing description, and the picking up of this relay will complete a circuit for relays W, ISU, iU and the winding 48 of relay UX in ...
