On major domestic railroads, a typical general merchandise shipment, or commodity, may pass through many classification yards on its route from origin to destination. At these yards, the incoming traffic, which may consist of several shipments, is reclassified (sorted and grouped together) to be placed on outgoing trains. On average, each reclassification results in an one day delay for the shi...

In this dissertation, we have developed computer vision methods for measurement of rail gauge, and reliable identification and localization of structural defects in railroad tracks. The rail gauge is the distance between the innermost sides of the two parallel steel rails. We have developed two methods for evaluation of rail gauge. These methods were designed for different hardware setups: the ...

The mini-project work undertaken by us involves the design & development of an automatic railway gate control and alarm system using Arduino. It has been noticed that a lot fatalities lives occur everyday due to manually operated rail gates. These happen mainly at places where road passes through city, locality or unmanned gates crossing zones. Currently, gatemen operate on assumption train...

A pricing methodology adapted to specific railroad infrastructures and the trains that use them is one way to ensure that railroad networks used by several different operators are used optimally. The diversity of railway networks (new lines and old lines) and services (long-distance and suburban passenger trains, freight trains, etc.) make it difficult to develop such a pricing methodology. Thi...
