Previous work has led to the development of a crash energy management (CEM) system designed to distribute crush throughout unoccupied areas of a passenger train in a collision event. This CEM system is comprised of crush zones at the front and rear ends of passenger railcars. With a consist made up of CEM-equipped cars, the structural crush due to a collision can be distributed along the length...

The Urban Rail Transit (URT) has been one of the major trip modes in cities worldwide. As the passengers arrive at variable rates in different time slots, e.g., rush and non-rush hours, the departure frequency at a site directly relates to perceived service quality of passengers; the high departure frequency, however, incurs more operation cost to URT. Therefore, a tradeoff between the interest...

We investigate a spectrum of decision-making approaches, from centralized to decentralized, within the context of scheduling direct and indirect (via a hub) trains and assigning containers to trains for the rail (linehaul) portion of the intermodal trip. The goal is to minimize operating costs, including a fixed charge for each train, variable transportation and handling costs for each containe...

In this paper, we have designed a machine visionbased method to identify the defected or missed or grounded rail anchors/fasteners that attach each line with the sleepers. Rail line inspection system is executed manually, especially in third world countries, like Bangladesh. This manual inspection is lengthy, laborious and subjective. To detect and classify the damaged or missed or grounded rai...

Rail shipments of hazardous materials expose the population near the routes to the possibility of an accident resulting in a spill. Rail routes are determined by economic concerns such as route length and the revenue generated for the originating carrier. In this paper we consider an alternate routing strategy that takes accident risks into account. We employ a model to quantify rail transport ...

Railway is an Eco-Friendly and Popular mode of Transport in most major cities of the World. One of the most widely used and comfortable nodes of transportation system is train. As the railway network is considered to be the safest and easiest network. More than 10 billions of people and 1050 millions of freight travel by train annually. Railway Transport is indispensable in modern day life, bot...

Train pathing is a typical problem which is to assign the train trips on the sets of rail segments, such as rail tracks and links. This paper focuses on the train pathing problem, determining the paths of the train trips in emergencies. We analyze the influencing factors of train pathing, such as transferring cost, running cost, and social adverse effect cost. With the overall consideration of ...

Due to the availability of precise satellite navigation systems, namely GPS and in the near future Galileo, which provide reference position, time and integrity information on a global and uniform basis, rail traffic is facing a revolution in terms of flexibility of operations. Autonomous satellite navigation receivers combined with a communication subsystem, so-called telematics systems, are u...

Abstract As communication technology improves and urban rail system develops, the new CBTC (Communication-Based Train Control) built upon train – train(T2T) has become mainstream of future transit signaling systems. In train-centered system, Train-to-Ground (T2G Train-to-Ground) mode may coexists with T2T mode. To reduce interference ensure reliable transmission information security, a joint ch...

Rail surface defects such as the abrasion, scratch and peeling often cause damages to the train wheels and rail bearings. An efficient and accurate detection of rail defects is of vital importance for the safety of railway transportation. In the past few decades, automatic rail defect detection has been studied; however, most developed methods use optic-imaging techniques to collect the rail su...
