In this paper, the effects on the wave shape will be studied according to the track permanent components such as rail, sleepers or ballast. The results show there is a step change in stress on the ballast layer. It is important to prevent the step change in the track characteristic module over 20%. It is also useful to provide a transition zone to allow the gradate changing in track characteristic module.
This research aims to develop the control process of manned railway level crossings depending on the modern control systems that contain microcontrollers, microprocessors, sensors, actuators, communications and software to compose smart automated sys tems that could be remotely monitored. The control logarithm and flow charts for all the functions that occur on the railway level crossing were used, depending on European standards (Safer European Level Crossing Appraisal and Technology, SELCAT) that aim to develop safety technologies on European railway level crossings. We designed a program to emulate all warnings and procedures that happen on the real railway level crossing, depending on the graphical Programming language (Laboratory Virtual Instrumentation Engineering Workbench, LabVIEW) that insures local monitoring on the crossing, and remote monitoring at the station and on the train via data network. By using the automated method, we were able to determine the approaching train to the crossing precisely, and insuring the provision of all warnings to road users and train driver to increase safety and reduce collision accidents between automobiles and train.
This paper presents the monitoring horizontal and vertical displacements of railway which heavy cranes run on using special geodetic techniques for the purpose provaiding rialway stability and safe working cranes on it. To quaranty that heavy crane s work safly, a rialway should be just horizontal– a small error of milimeters leveling is allowed according to working conditions for cranes. A rialway shoud also maintain its spaces to facilitate the crane motion on it. Monitoring railway vertical displacements involve measuring the relative vertical displacements of target points that are distributed along the railway in two cases: static and dynamic. vertical displacements determined by precise leveling which are performed using digital high accuracy level. The precise leveling measurments of target points have been connected to stable benchmark that are located in surrounding terrain of railway for purpose of further studies. In this paper the alignment method was used to monitoring the railway horizontal displacements using digital rulers and total station provided by a prism fixed forcely on the railway. This is done by measuring the small bias angles of the targat points which are distributed along the railway. This research has illustrated the efficiency of alignment method in order to calculate the horizontal displacements of railway axis.
This research provided an analytical study of Two basic variables Which are cost and revenue in railway transport Institution, based on the laws relating to the rail system. The researcher found that different Syrian railways standard gauge railway system (display tracks 1405 mm) makes the Syrian railways non-compete globally, in addition to being unused or underutilized in many Syrian cities, which is The major problem. The importance of research that the use of this type of rail would bring profits and losses of economic and financial terms, as in most of the railways in Europe and the United States and Japan, if you rely on the new shape of the railroad in Syria based on comparative analysis of both the costs and revenues. The researcher adopted on the descriptive analytical metgology to analyse the cost and revenue data for each of the rail transportation and ground transportation for the period from 1980 to 1987. The researcher reached the most important set of results, the analysis of the financial situation of cost and revenue of the new railway transport of goods and passengers is equal between transport by truck and rail transport, while cargo operation on the roads by truck is a Losing process..
