Routing Trains Through Railway Junctions: A New Set-Packing Approach

Arguably the most important decisions facing railway companies today concern the effective utilization of available resources. One such problem, the motivation for this paper, entails allocating the track capacity of a junction to a timetabled set of trains so as to ensure quality routings are obtained. Large junctions are highly interconnected networks of track where multiple railway lines mee...

Study on new crashworthy buffers in railway

At the collision time, a lot of energy is generated during a short period of time that causes large deformations in bodies. One of the most important parts of wagon in railway is a buffer which may absorb the energy during an impact. It should be mentioned that normal buffers only absorb the energy resulted from a crash elastically. In the present paper, it is tried to use inversion mode of ...

On-line Appendix

Random alarm clocks In a number of the constructions of this appendix, we rely on so-called random alarm clocks, which in most cases are used to set the duration of “punishment” for a player who has failed to do a favor. These random alarm clocks always have durations that are exponentially distributed, meaning that if the clock is “set” at some time T0 , it goes off at time T0 + t or earlier w...
