How the planned V0 railway line would increase the resilience of the railway network of Hungary against attacks

TL;DR

The paper evaluates how the proposed V0 railway line in Hungary could enhance network resilience by redistributing traffic and providing redundancy against bridge disruptions, based on analysis of four alternative routes.

Contribution

It introduces a detailed analysis of four V0 railway line alternatives and their potential to improve Hungary's railway network resilience against attacks.

Findings

V0 line could significantly redistribute network flow.

V0 line provides redundancy for existing bridges.

Analysis of four route alternatives shows varying resilience improvements.

Abstract

The spatial distribution of the railway crossings on the river Danube in Hungary is very uneven. There is only one electrified and double-tracked bridge in the country, the Southern Railway Bridge in Budapest. The \'Ujpest bridge in Budapest only provides connection through line 4 which is not electrified and the Baja bridge is not electrified, too, and both of them are single-tracked. The long-planned V0 railway line that is to be cross the Danube approximately halfway between Budapest and Baja would not only help to redistribute the total network flow which currently passes through almost exclusively the Southern bridge but would also provide redundancy for the existing bridges in the case of their disruption. Four of the five proposed V0 path alternatives are analyzed on the basis of these two network properties.
