Animal-train collisions are increasingly serious challenge for modern railways

Scheduling Train Crews: a case study for the Dutch Railways

In this paper the problem of scheduling train crew is considered. We discuss a general framework of which the method for solving the train crew scheduling problem is a special case. In particular, our method is a heuristic branch-and-price algorithm suitable for large scale crew scheduling problems. This algorithm is applied to a real life train guard scheduling problem which is provided to us ...

Are Animal Models Relevant in Modern Psychiatry

The use of animals in medical research became firmly established in 1865, with the publication of An Introduction to the Study of Experimental Medicine by Claude Bernard. This scientific discourse laid the groundwork for the study of comparative physiology between animals and humans. Half a century later, the animal model was introduced into the behavioral sciences by early theorists Pavlov (cl...

Multi-Agent Communication Based Train Control System for Indian Railways: The Structural Design

Indian Railways (IR) work on static block signaling (SBS) system to control mixed train traffic. Current state of operation can be improved by using communication based train control (CBTC) system with moving block signaling (MBS). The mixed traffic conditions in IR restrict the direct use of CBTC systems used elsewhere and thus first necessitated study of existing CBTC systems followed by deve...

A simulation tool to support signalling and train control design for high-capacity railways

New-generation signalling and train control systems, such as ETCS-level 2, distance-to-go ATC and many CBTC implementations, effectively transfer responsibility for safe train separations from track-based ‘fixed block’ sections to dynamic on-board calculations using data from speed sensors. Signalled line capacity, in terms of trains per hour, is thereby directly dependent on true train speed, ...
