At the beginning of 1820s. Marc Seguin and his brothers started negotiations with French government for the construction of a railway line from the Saint-Etienne coal field to the Rhone valley and the city of Lyon. This railway is the first French railway using locomotives. Because there are few papers and publications on the history of this important railway, the writers have studied about the...

in this article, multiple-product pvrp with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. a mathematical formulation was provided for this problem. each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. to solve the problem, two meta-heuristic methods...

Occupational statements on death certificates of 2,457 males aged 25-64 who died from bladder cancer in selected coastal and estaurine regions of England and Wales during 1965-1980 were studied. Excess mortality was found for deck and engine room crew of ships, railway workers, electrical and electronic workers, shoemakers and repairers, and tobacco workers. An excess of cases also occurred amo...

This paper describes a railway system simulation to be used by train railway system operators. We have developed a learning tool for education, but, besides, different railway system models can be analyzed. Wedonot need to build the physical railway model, but may experiment with the planned system on the computer. The modeled system can be built easily and effectively and its behaviour may be ...

Safety and security and considered a critical issue in railways. Applying geographic information system (GIS) and Global Positioning System (GPS) in the railway becomes very important. Web-based GIS makes it easy to exchange information and create better public communication through the Web site. It helps to plan for a trip by checking train times, stations and different lines between stations....

Railway yard is the basic composition unit of railways, therefore, the efficiency and quality of railway yard design have a crucial effect on the construction and operation of railways. Plane design is the basis and core of railway yard design, consequently, it is significant to research plane design of railway yard. In this study, through analysis and summary of the research status as well as ...
