To meet the increasing demands for passenger data rates, modern railway communication networks face significant challenges. The advent of 5G communications after long-term evolution (LTE) and LTE-Advanced (LTE-A) systems provides several technological advances to address these In this paper, reviewing main aspects railways, we describe seven challenges faced by train connectivity, discuss appro...

in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...

It is quite appealing to base the description of pattern-based searches on positive as well as negative conditions. We would like for example to specify that we search for white cars that are not station wagons. To this end, we define the notion of anti-patterns and their semantics along with some of their properties. We then extend the classical notion of matching between patterns and ground t...

This teaching case examines the implementation of a new technology for tracking individual freight railcars (wagons) by Indian Railways. After exploring multiple ‘technological options,’ the Indian Railways decided to undertake a pilot project based on timetested Automatic Equipment Identification system using Radio Frequency Identification (RFID) technology. However, a number of other technolo...
