eggs (Webster, 1934). The results of that investigation showed that much reduced pressures were insufficient to destroy the eggs. The question is one of great importance to administrations involved in the carrying of passengers in vehicles; it is of particular importance to railway authorities in India, where constant reinfestation of passenger vehicles takes place and where conditions are emin...

In this paper, we describe a new model for the Train Unit Shunting Problem. This model is capable of solving the matching and parking subproblems in an integrated manner, requiring a reasonable amount of computation time. Furthermore, the model incorporates complicating details from practice, such as trains composed of several train units and tracks that can be approached from two sides. Comput...

China’s railway network is one of the largest railway networks in the world. By the end of 2016, the total length of railway in operation reached 124,000 km and the annual freight volume exceeded 3.3 billion tons. However, the structure of network does not completely match transportation demand, i.e., there still exist a few bottlenecks in the network, which forces some freight flows to travel ...

Now a day’s Railway systems plays a key role in transportation in the world. The demands for the trains are increasing drastically. The demand also increases the update of technology day to day. The train journey should be more secure. One of the problems in railway transportation is gate control system. Presently in railways the gate is controlled by manpower. Whenever the train arrives, that ...

Planning new railway infrastructures is a complex process. We present an approach where the formalization of expert knowledge regarding the railway domain is motivated in order to improve the planning process. By applying ontologies as a representation of railway related knowledge we are able to make the coherencies of infrastructural elements explicit. Furthermore the integration of an ontolog...

User assignment models in transit networks are relevant for the planning of new lines but less management. Other types used management, which is very efficient simulation supply users, who nevertheless influence train traffic on urban railway lines. This paper proposes to use a combined and passenger model line propose management solutions order minimise travel time. An application this method ...

The aim of this paper is to apply a new categorisation algorithm to an existing database of case studies in order to investigate its effectiveness in sorting unknown train vibration signals into freight and passenger train categories for exposure-response analysis. Relatively little work has been performed on the human response to vibration from railway transportation when compared with respons...

Today the railway timetabling process and the track allocation is one of the most challenging problems to solve by a railway company. Especially due to the deregulation of the transport market in the recent years several suppliers of railway traffic have entered the market in Europe. This leads to more potential conflicts between trains caused by an increasing demand of train paths. Planning an...

This paper deals with real-time disruption management of rolling stock in passenger railway transportation. We describe a generic framework for dealing with disruptions of railway rolling stock schedules. The framework is presented as an online combinatorial decision problem, where the uncertainty of a disruption is modeled by a sequence of information updates. To decompose the problem and to r...

Passengers experience significant inconvenience from track closures required for planned maintenance and infrastructure updates of rail networks. Generally, operators restore connectivity with shuttle busses replacing the closed link in the network. This however introduces additional transfers, while the speed of travel on busses for the replaced links is generally lower than the speed of the p...
